Are
the Waters of the East Different from the Waters of the West?
Slowly, but steadily, physical treatments of water with magnetic fields
become known and accepted in the Western World. They have been utilized
since about 25 years in many countries of the Eastern World, the USSR and Mainland China
for instance. There, hundreds of success- reports have been published,
most of them admitting the lack of a fully satisfying scientific
explanation. These papers describe - often in great detail - the
observation of reduced formation of hard lime scale, the elimination of
old lime scale deposits, accelerated plant growth, desalination of
soils, improvement of concrete, better cleaning, faster drying, better
taste and smell of drinking water, changes of freezing modes,
beneficial effects on patients with kidney stones, and minute changes
in some physical constants of the water, such as viscosity, IR
absorption, surface tension, to name just a few.
Many of these reports are authored by scientific teams of universities
or government agencies, describing years of experimentation and
subsequent routine applications in larger forms. Resulting savings in
the use of chemicals, of energy, and of equipment are substantial,
according to these reports.
But
Contradicting these descriptions originating from Eastern countries are
a number of reports of tests and checks by teams working in countries
of the West. No change of the water was found by magnetic treatment
according to some of these reports. Some of these evaluations concede
to find some effects when long-time observations were made.
In a number of States within the USA magnetic water
treatment has officially been declared to be a hoax or its
advertisement has been outlawed to be fraudulent.
How can such discrepancies of opinion exist for tens of years in our
small and supposedly communicative, scientific world?
A number of reasons for different opinions are caused by a number of
obvious differences in the circumstances prevailing in the respective
countries, for instance:
The peoples of the Western world insist to be
able to understand what they are doing or using. Theoretically
unexplained processes have the stigma of black magic or superstition.
The West is used to and takes for granted the
unrestricted availability of chemicals for all purposes in reliable
quality and purchasing price which is not so in many countries of the
East.
The Russians do not have a particularly good
reputation in matters of research on water after the disaster of the
claim by Deryagin to have found the “Polywater“ in the 1960's (The
history of this scientific misfiring is well presented in FELIX FRANK'S
booklet Polywater, the MIT Press Cambridge, MA. 1981).
The Free-Enterprise system permits anybody to
take advantage of potentially fast profits with wild claims about an
important item, such as water. Many partially informed or irresponsible
sales-people give the entire issue a bad name by false promises, such
as “No need for chemicals!“ The Correct statement would be: “Chemicals
become more effective in magnetically treated water, so that one needs
chemicals in reduced amounts.“
What is Magnetic Water Treatment?
(As described by Russian papers)
A number of conditions are given in the Russian papers about the
details of their experiences; here are a few:
The water to be treated has to move across
magnetic fields not stronger than 1000 to 2000 Oersted.
For a certain flow-velocity the effect
is a maximum.
It usually works better for water of a lower
temperature.
Some small changes of the physical constants
of the water last only for a few minutes.
The capability of the water to prevent
formation of hard lime scale may last for up to 2 days.
Instead of forming hard lime scale (“Slake“)
clinging to the walls of the container, the calcium carbonate of
magnetically treated water forms a soft sludge (“Shlam“), flowing with
the water.
Reliable observations of the effects of the
magnetic treatment require several weeks. Many attempts of faster
results have not always been conclusive.
The magnetically treated water is able to
dissolve formerly deposited lime scale.
Soil can be de-salinated.
Harvests are significantly improved in
quantity and quality.
Our own Experiments and Observations
Prospects. Confronted
with the challenging discrepancy between 400+ computer references of
papers from the East and a score of opposing, critical surveys from
Western countries, we probed into the matter experimentally. We had the
facilities of the CaliforniaStatePolytechnicUniversity,
Pomona,
at our disposal, where the author has been teaching Physics for 10
years, and acoustics just at this time. The author had been working in
materials research for most of his professional life, permanent
magnetism and crystallography being his specialities. He was familiar
with the many unsolved puzzles of water by his early works as a physics
student in Cottingen,
Germany.
Why is there lime scale?
The formation of hard lime scale at the container walls by the CaCO3
content of water is a consequence of the scarcity of nucleation centers
in ordinary water. When the concentration of the CaCO3 exceeds the
solubility, the solidification can begin only at appropriate starting
points most of the time at foreign matter. If no foreign matter is
present in the form of particles in the liquid, solidification can
start only at the walls of the container. Ordinary water tends to
surround any foreign particulate with complexes of 100 to 200 water
molecules each. The water molecules agglomerate around every foreign
particle in ordinary water. They form cages around them which makes
them ineffective as nuclei. Then, the container walls are the only
non-water substances available. The resulting crystals are of the
dendritic mode. They are characterized by few starting points attached
firmly to the wall and extended systems of crystals clinging to one
another and to the wall around the starting point. The dendritic
crystallization mode is the initiation of the formation of hard lime
scale which, if further solidification of the mineral occurs, grows
layer over layer on the first set of dendrites.
Early detection of lime scale.
Microscopic observation of the beginning of crystallization in the form
of dendrites reveals the tendency for scale formation immediately. We
placed drops of water on glass slides and permitted the water to
evaporate under observation with magnifications from 50 to 400 times.
The microscope was equipped with polarizer and analyzer in order to
improve the contrast for the optically active CaCO3 crystals. We
compared drops of ordinary water as it came from the tap with drops of
the same water after it had passed through magnetic fields; the drops
were evaporating side by side on the same glass slide under identical
conditions.
Magnetic effects?
The area formerly covered with the water is now covered with a lattice
of thin dendritic crystals, the rim of the drop is studded with a
number of thick, strongly light-polarizing dendritic crystals which had
grown each from one point at the glass on the periphery of the drop.
These crystals were firmly attached to the glass of the slide; they
fractured if one attempted to dislocate them with a microscopic needle.
This entire drop periphery contained 124 such prominent crystal
systems.
The entire drop circumference contained 41 such crystals. So: The
number of these crystals which had grown on the glass was reduced by
about two thirds by the magnetic treatment of this water. The
effectivity of the treatment with respect to reduction of such
glass-attached crystals was therefore 67%. Assuming that these crystals
are the start of scale formation, the magnetic treatment would have had
an effectivity of 67%.
An economical quantitative method.
This simple method of comparing the microscopic crystal count without
and with the magnetic treatment permits within hours a quantitative
estimate of the effectivity of the treatment with regard to scale
reduction. The counting is greatly facilitated by the fact that in a
circular water drop on a glass slide, almost the entire mineral matter
solidifies at the outer circumference of the drop. This was found to be
caused by a convection within every circular drop of evaporating water.
This convection is caused by the evaporation cooling at the surface of
the drop; it transports the heavier substances within the drop radially
from the center to the outer perimeter of the drop where they become
concentrated and solidified. Furthermore, after counting all crystals
of the entire perimeter of many drops it was found that the
distribution of the crystals along the perimeter is even enough that
the crystal count within a section of only 1/12 of the entire drop is
usually representative for the entire drop.
With this straight forward and economical working scheme we
investigated the effectivity of magnetic fields for various flow
velocities, for various numbers of magnets, for different pole
arrangements and for different waters.
First findings.
The relationship between effectivity and flow velocity had in almost
all cases a maximum for one velocity. The plot of the values had the
shapes of resonance curves. Variations of the distances between the
magnets confirmed the relation between the flow velocity and the
sequence of the fields crossed by the water, as indicated by the two
curves.
Magnetic arrangement.
Hundreds of field arrangements have been tested with a number of
different water types. Maximum effectivity was achieved with
arrangements where the fields originated from simple, ring-shaped
permanent magnets of barium ferrite of a medium grade. The arrangement
was granted a US Patent in 1981. By “tuning“ such a device to a certain
water velocity the effectivity of such a device could be brought close
to 100% with 8 ring-magnets. Water which contains a large amount of
admixtures shows additional effects if it passes repeatedly through a
magnetic device. The admixed algicides, bactericides, and softening
chemicals produce an extended dendritic crystallization over the entire
area of the evaporated drop.
The formerly hidden foreign particle becomes available to the over
concentrated calcium carbonate, so that the dissolved calcium carbonate
diffuses to this particle equally from all sides simultaneously. So,
the typical circular disk shape of a seeded crystal appears. If the
effectivity of the magnetic treatment was high, no calcium carbonate
needs to wait to diffuse to the container wall in order to solidify.
Therefore reduction of the hard scale formation can be understood as an
internal seeding effect in the magnetically treated water.
Entropy/Energy
Skeptics might doubt this process to be possible because the former
mixture of liquid water and liquid calcium carbonate is being turned
into liquid water and separated, solid calcium carbonate. This unmixing
means a lowering of the entropy of the system. Any entropy lowering
requires the expense of energy which cannot come from the permanent
magnets. The needed energy can only be delivered by the kinetic energy
of the flowing water. For this reason, no effect can be expected if the
water does not move.
Can this process also accomplish the often
doubted claim of removal of formerly deposited hard lime scale?
Having no restriction for the solidification of the calcium carbonate
thel iquid water is soon depleted of dissolved calcium carbonate.
Having some of the large cage-clusters in pieces the depleted water is
particularly active (reduced viscosity and surface tension). If the
water streams passed calcium deposits, it replenishes its calcium
carbonate content by dissolving stationary solid calcium carbonate. It
may be mentioned here, that in many cases of rather thick deposits, the
dissolving does not precede piecemeal from the outer layer, as the
customary acid washes do. The magnetically treated water rather weakens
the bond between the wall and the calcium carbonate, so that the scale
breaks off in rather large pieces from the walls on which they had
grown. This dissolving process may take several days or even weeks. But
under advantageous circumstances only hours may be required to loosen
old, hard deposits and render them removable.
Can water have a memory?
According to many reports of success, the water retains its capability
of reducing scale for up to 2 days. Critical comments try to make this
fact appear to be absurd by calling it a “memory“ of the water for its
“magnetic experience.“ We realize that the treated water has its
specific scale reducing capability as long as its calcium carbonate is
in the solid form of the inert micro crystals.
We have investigated these crystals with high magnification for many
different waters and varied treatments. Using the interference colors
of the polarized light the thickness of the disk-shaped crystals can be
estimated to be from 0.1p. to 2.4p. (About 4 times the wavelength of
red light).
Transformation in the solid state.
With hundreds of evaporated drops of different waters under continuous
observation before and after various treatments, it is one of the most
astounding findings that these dry, seemingly immobile crystals,
sitting on the glass slides, keep changing their mode for weeks in
their solid state.
Most significant is the transformation of the disk-shaped circular
crystal platelets. After about 20 hours they develop holes in their
centers and some of their matter turns into thin needles bundled up at
the location of the disk. The disk-shape is a meta-stable crystal form
of calcium carbonate; it transforms into the more stable form of
acicular crystals within days. These needle-shaped crystals then
dissolve also, most of them last only 2 or 3 days. That is the reason
for the fact that the scale-reducing properties of the treated water
last for 2 days only.
For more research.
Many questions remain for more investigations. The influence of
temperature has not been investigated as yet. It can only be assumed to
be of essence according to Russian reports. Also, the type of the water
from different sources seems to be of importance. Some mountain spring
waters require particularly well adjusted magnet sequences in order to
be effective. According to findings by geologists about the type of
mountain water coming from narrow spaces of defect structures within
mineral deposits, such water may have formed only few complexes of a
specific size. Therefore the required resonance is a narrow one and
therefore difficult to achieve.
The effectivity of the magnetic treatment may
also be influenced by certain mineral contents of the water - such as
silicates - which appear to interfere with the magnetic treatment.
Freshly fallen rainwater did not show much effect from the magnetic
treatment. It has been found to contain as many seeded disc-shaped
crystals as water after the magnetic treatment! It is believed that the
raindrops passing on their way down through the electric fields of the
clouds may undergo a sort of natural treatment with electric fields.
The actual physical changes of the water.
Another wide open field of questions remains to be investigated; that
are the short-lived effects of magnetic fields on the physical
constants of the water. These effects are so minute that their
measurements are beset with uncertainties. Yet their effects for the
usefulness of the water are often of great importance, as for instance
the surface tension which determines many parameters of the water
quality. A number of experiences are reported from many sides, and some
of our own observations with respect to these changes in the physical
structure of liquid water will be mentioned in the next section.
Learning more about liquid water.
Assuming that the interactions between magnetic fields and moving water
are of the nature which are here proposed, the study of magnetic water
treatment opens new avenues for the study of the structure of liquid
water. So far, no systematic study has been attempted of this issue.
Nobody doubts the overwhelming importance of the use of water for
virtually every human endeavour, yet there is no correlation which
could oversee all the many separate researches into water by the
various users. (In the 6 volumes of his comprehensive treatise “WATER,“
Felix Franks decries this fact and has tried in his lifetime to change
this lack of concerted effort.) The magnetic water treatment issue
might be one way to make the few known facts of the physical structure
of water more generally available. One important step in this respect
is that the general public learns that there are fundamental problems
with the physical structure of water.
At this time, even the more sophisticated users and investigators of
water think most of the time only in chemical terms of the water.
Almost without exception, “testing of water“ is considered a chemical
analysis. Understanding the nature of the magnetic treatment of water
as to be only a phase-change of some components of the water, it is
evident that any chemical analysis of the water before and after the
treatment cannot possibly show a change. The magnetic treatment does
not actually add or remove anything from the water. A standard chemical
analysis brings all the substances into an all over dissolved state,
thusly undoing the effects of the magnetic treatment. Many negative
test results have been published because of this exclusively chemical
thinking.
Again, it has to be said that many of these misconceptions have their
origin in the misrepresentation of the method by insufficiently trained
sales personnel. They try to compare the effects of the magnetic
devices with softening chemicals or ion exchangers. So, the water users
are disappointed and consider the entire issue a swindle.
What are the Consequences for Future Water
Usage For Industries?
Simple magnetic treatment units with their best effectivity at a fixed
water flow rate serve with advantage in such installations which
require a constant flow rate. The size of the treatment unit can be
selected to fit the exact requirement of the machinery.
Very small units may serve in drip irrigation at every separate outlet
with one gallon/hour flow rate, or a larger unit may be used for the
entire irrigation system. Ice machines, solar panel, steam cleaners may
have a precisely fitted magnetic unit permanently built in. Without it
they would plug up within a few weeks of use and would have then to be
washed out with acid to remove the accumulated hard lime scale. The
built-in magnetic units keep these machines running for many months
without an acid wash.
In the case of steam cleaners, an additional benefit results from the
lessened surface tension of the magnetically treated water. Oral,
unpublished reports of increased cleaning power of detergents confirm
the microscopically found change of the water-detergent mixture.
Instead of the drop circumference which is usually well defined by the
surface tension, the treated water wets the glass surface much better
improving the activity of the added detergent.
Another potential application of magnetic water treatment has been
looked into for the oil industry. The fossil water which comes up with
the oil is extremely heavy with minerals. Its separation from the oil
and subsequent replacement under ground can be facilitated by magnetic
treatment.
Some preliminary investigation (non-published) was successful for one
narrow range of flow rate. The massive dendritic crystal growth has
been replaced with a multitude of small, rectangular crystals. Much
further investigation is needed to reap the potential benefits from
magnetic water treatment for a number of problems of the oil industry.
As for instance a better separation of the oil from the water.
Magnetic
Treatment of Water and its application to agriculture - Lin
By Dr. Israel J. Lin and Jacob Yotvat,
Technion - IsraelInstitute of Technology,
Haifa32000, Israel. In
controlled large-scale field experiments it was found that
magnetic treatment affects the quality of irrigation water. It was
shown that treated water contributes to an increase in farm yields in
crop farming, yield being expressed in quantity and quality of the
produce añd in the specific economic contribution. The level of
return in individual farms depends on three key factors: the type of
equipment, the water quality, and the mode of operation of the
apparatus. In this work reference is made to the principles of the
method, the range of possible applications in agriculture, and a report
on field observations. Sporadic
references can be found in professional and popular literature to
exposure of irrigation water to external force fields (mechanical,
hydraulic, ultrasonic, electric, magnetic) with descriptions of
resulting improvement in field—crop yields— vegetables, fruits, etc. As
regards magnetic treatment, it was reported in use in Eastern Block
countries like U.S.S.R. and China [1,2], and to have proved effective
for a wide range of crops. Hitherto, however, no systematic examination
of the phenomenon was attempted; there were no publications on the
underlying principle or mechanisms, nor was any commercial equipment
offered in the West for controlled treatment of irrigation water. Five
years ago, following infrastructure studies, a research program was
drawn up and a large scale series of field experiments was
initiated, with a view to examining the effect of this treatment on
agricultural yields in Israel. Original equipment
was devised, several models were constructed on the basis of
comprehensive complexes, 14 experimental sites were established at
agricultural settlements (privately owned and collective
farmsteads),and the program was launched. A limited number of
prototypes were adopted selectively for examining the effectiveness of
short—term exposure of drinking and irrigation water, with the
apparatus installed upstream and the water delivered for consumption by
livestock and crops downstream. Water
is a cardinal factor in crop farming, involving a wide range of aspects:
Quality and quantity;
constituents (solutes, suspensoids) and the mode of their presence.
Mode of delivery; type of
irrigation system (with or without inclusion of fertilizer in the
stream).
Irrigation schedule;
distribution of the water in the soil, mode of penetration and
migration.
Use of sensors and
regulatory devices, with a view to control of the mass—transfer rate in
the porous medium (soil) and for delivery of the water at the
appropriate location and time.
Information management,
automation.
Purification pretreatment
(filtration, ion exchange, RO, hydrocycloning, etc).
Controlled quality and
delivery of the water made for improved crop yields. It is common
knowledge that irrigation played a strategic role in the on—going
process of evolution and in the development of civilization, and is the
cornerstone of all agrarian planning. As a “universal” fluid substance,
it has unique properties and a specific structure directly related to
the hydrogen bond. The two hydrogens and the single oxygen are
arranged non— rectilinearly, with a bond angle of 104.5 degrees. The
abnormal physical properties of water include [31:
Negative volume change during
fusion.
Maximum specific gravity at 4
degrees C.
Minimum isothermal compression
at 46 degrees C.
Multiple polymorphism.
High dielectric constant,
surface tension and dissolution capacity.
Fusion and boiling points
relatively high for a non-metallic, non ionic material with a
relatively low molecular weight.
High mobility of hydrogen
and hydroxyl ions.
The irrigation regime is of
paramount importance in that it determines the availability of water
and nutrients (in terms of dosage, distribution and loses), improves
crop yields (in terms of quantity, quality and uniformity), and
regulates soil aeration. For example, subsurface dripping has the
following advantages:
Reduced evaporation loss and
reduced mineral accumulation of the surface.
No surface runoff; no danger of
accidental damage by animals or machinery.
Absorption variability over the
surface —irrelevant.
Negligible effect of temperature
on uniformity of distribution.
Vertical percolation
controllable through timing.
Reduced wear of piping.
The objective here is increased
yields, improved quality, and higher utilization efficiency of the
irrigation water. The proposed magnetic treatment of irrigation and
drinking water is intended for exactly the same purposes. The
treatment is essentially physical, and its intensity increases with the
rate of flow (up to a certain limit) and with the electric conductivity
of the water. In view of the latter, it is suitable for fresh water and
all the more so, for effluents and saline water. For satisfactory
performance, the following measures are mandatory:
(a) Suspensoids must be removed
by filtration — especiallyferromagnets, which adhere to the magnet and
may cause clogging and distortion of the magnetic field. (b)
The size of the apparatus must be adapted to the envisaged consumption
level. (c)
The apparatus must be installed vertically. (d)
Periodic maintenance must include direct and back-flushing.
The treatment is applied
upstream, near the point of delivery to the soil, and is suitable
for the various modes of irrigation:- surface and subsurface dripping,
mobile sprinkler, spray, and flood lines. Efficient
and continuous performance is effected hydraulically, hence the magnet
remains serviceable for many years. This is important, as the service
life of the apparatus should be of the same order as that of the other
system components (refer to Table 1). Servicing requirements are
minimal, and so is the annual per-unit-plot expenditure on the capital
investment.

Further
experiments are in progress on cotton, grapefruit, melons and tomatoes
- with soil, water quality, and climate (location and season) as
variables [67] DISCUSSION Future
availability of water for Israel’s agriculture is
problematic, because of depletion of the present sources and the
imbalance between consumption and developmentof new ones, with the
attendant cumulative deficit. Reduced availability is especially likely
with regard to high-quality water, hence the importance of physical
treatment. The plans of the Israel Water Planning Authority and Water
Commission for the early, 21st century envisage an annual consumption
level of 1300 million m3, including 400-500 million in effluents. An
increase proportion of effluents and saline water, with the dissolved
electrolytes providing higher electric conductivity, is actually an
advantage from the viewpoint of magnetic treatment. In
developing the proposed technology, emphasis was placed on basic
magnetochemical and magneto-hydro- dynamic principles, with a view to
engineering-wise and optimization of the equipment. Design
prerequisites are as follows:
Maintenance of suitable
(laminar) flow regime.
Compatibility with given
conductivity range and types of solutes.
Appropriate relative orientation
of magnetic field and flow.
Appropriate range of
magnetic field intensities and gradients.
Comprehensive design of special
magnetic circuits.
Appropriate permissibe water and
ambient temperature ranges.
Prevention of other
electromagnetic effects in the vicinity of the apparatus.
Appropriate choice of
construction materials.
Appropriate modes of assembly,
installation and maintenance (general and preventive).
Similar results were observed in
animals and in plants, indicating similarity of principles and
mechanisms in both cases. Some of these parallels are summarized in
Table 6.

In addition to the magnetic
treatment being a production factor, it should be evaluated in the
context of its suitability for a wide range of distinct crops in
different agri-climatic environments. In the era of modern agriculture,
it is natural to consider the contribution level of the proposed
process against the background of the sophisticated techniques of
intensive farming. The processed medium being water, the process is
intended not as a substitute but rather as a reinforcement for the
conventional means of increasing yields and improving qualityat lower
cost- the last name feature being a sine qua non for world-wide
competitiveness.
CONCLUSION
In the present research project,
the preliminary feasibility study has been successfully completed, and
intensive field work is in progress in an attempt to prove the proposed
technology over a wide range of application and conditions (soil,
climate, water quality, crops, etc.); evaluated the main parameters
governing the effectiveness of the apparatus; reduce the farmer’s risk
while perfecting the equipment; achieve overall optimization of
the magnetic circuit, engineering-wise and operationally; and,
finallydetermine the cost benefit indices. The
proposed treatment is a technological contribution to modern
industrialized agriculture, and isthe outcome of initiative and
innovation the part of the inventors and of the collaborators whose
farmsteads served as sites of development and centers of demonstration.
The magnetic apparatus should be regarded as a production tool
alongside the other elements: irrigation
equipment, seeds, fertilizers, pesticides, nursery equipment, plastic
covering, hydroponic beds, etc., which are the principal factors (not
counting labor) in reaching new peaks of quality and quantity. It will
be the farmer who shall eventually decide, in the light of the above
description and of the field evidence, whether the proposed process is
to be included in the “technological package” available here today.

Microscopic
Fuel Tests Using Magnetic
Fuel Conditioning
by Dr. Klaus J. Kronenberg (1991)
After 45 years of experience as a physicist, studying magnetics,
acoustics and crystallography, Dr. Klaus Kronenberg, in conjunction
with other Research efforts, has developed an exciting new theory of
magnetic fluid treatment.
Investigations and results
Empty glass slides were held for several seconds in the exhaust stream
of a V-8 gasoline engine using leaded gasoline running at 2000
rpm. Fig.1 No Treatment. The droplets at
highest magnification show a spherical structureless shape. All slides
exposed to the exhaust without Magnetic Treatment showed a multitude of
small droplets clinging to the glass. They were distributed over the
entire glass slide at even distances. They did not evaporate over days.
Their shape became visible in the microscope using polarized light.
Fig.2
No Treatment. Remains of a solid particle from the exhaust which
bounced off the glass slide. Figure 2 is an
example of a shapeless bit of matter clinging to the glass. About 10
such places were found with similar shapeless matter on the glass
Fig.3 Exhaust of
Magnetically Treated Fuel. One of the round spots found on the glass
slide exposed to exhaust from Magnetically Treated gasoline.
The slides which had been exposed to the
exhaust when the magnetic device was in place on the fuel supply line
were also full of the small droplets, but additional material was
discovered clinging to the glass. This material formed roundish spots,
about 10 to 30 per slide. The details of the round spots were most
visible when side-illuminated. Many contained a black particle in them,
which was often broken up. All the rims of the round spots were
heavily scalloped, exhibiting just enough surface tension to form the
roundish appearance of the spot on the glass slide.
Fig.4 Exhaust of
Magnetically Treated Fuel. Stronger magnification and side illumination
reveals scalloped shape of the rim of this substance (low surface
tension indicated). The
side-illumination reveals the scalloped rim of the spot. The traces of
the gradual evaporation within the spot are visible and show that the
evaporation ended at the particle.
In order to obtain more information about the nature of the material
which formed the rounded spots they were observed with polarized light.
Within the roundish spots crystalline shapes appeared with a variety of
configurations. Most of the shapes were crystals of a dendritic type.
Large numbers of smaller, nearly cubic crystals were also found. All of
these crystals are of an optically active material, recognizable on the
dark-light contrast within each crystal in the polarized light. The
shape of the crystals point toward the crystals having a cubic crystal
structure, being most likely a lead compound. CONCLUSIONS
The consistent results of both test series permit a cautious attempt at
explanation. The fact is that the slides covered with exhaust without
the magnetic fuel treatment showed only the tiny droplets, but not one
single round spot. But, the round spots were found in abundance on the
slides from exhaust with magnetic treatment. This makes it almost
certain that the magnetic device on the fuel supply line had an effect
on the combustion of the fuel in the engine.
The roundish shapes of these spots are evidence of the fact that they
must have been splashed onto the glass as a liquid. They must have been
in the form of spherical drops in the exhaust. Their sizes imply drops
at least 1000 times heavier than the droplets found in the exhaust of
the untreated fuel.
The dark particles found inside these roundish spots indicate that a
solid particle was transformed in the combustion process partly to a
liquid. This could have happened in the form of a partial combustion.
Not one roundish spot of a similar size has been found in the exhaust
of untreated fuel. This suggests, that such partial combustion of
certain larger particles has not been occurring without the magnetic
treatment. In the exhaust of untreated fuel we find instead, evidence
of some larger solid particles which have left some formless traces
after hitting the glass and flying off. They showed no trace of a
liquid by a partial combustion.
The investigated fuel is a mixture of many components containing
benzene-like ring-molecules. The refining process - heating in the
absence of oxygen - had used the internal vibration of the large
molecular sheets to have them break up. The molecular fragments were
driven off, collected and separated. Their size determined their
ability to resist combustion.
The results of our tests with the application of a number of magnetic
poles which the fuel had to pass on the way to the engine can be best
understood as an additional effect of fuel refining. We suggest that
some larger molecular structures remained in the fuel after the normal
refinement process, because they withstood the breakup effect by heat.
They were then broken up when they passed through the series of
alternating magnetic fields. The magnetic effect on molecules is very
weak. But it is known that it can be amplified a million fold in the
case of resonance. If the time sequence of the alternate magnetic
fields encountered by the streaming fuel hits a frequency of the
internal vibration of a molecular structure, then a resonance occurs
and may break up the structure which had escaped the breakup by the
original refining process. This renders the original refining process
more complete.
Therefore, we think we can predict that the effect of magnetic fuel
treatment will be best for the least completely refined fuel.
Further research is required in order to confirm the findings. Possible
differences for different fuels (Diesel), varied rpm's, and varied
arrangements of magnetic fields are being explored.
Magnetic
Neuromedicine An "Attractive" Promise
FRANK ADAMS, MD, FRCPC, DAAPM American
Journal of Pain Medicine
MAGNETISM is one of the fundamental forces of
nature---a phenomenon known and speculated about, studied and utilized
in one manner or other since antiquity. It is most commonly associated
with the compass---a direction finder which, in the West, dates from
the 13th Century---that revolutionized navigation and pointed the way
to the New World. It is a long
voyage from the ancient high seas to modern medicine, but recent
developments indicate that this ubiquitous force may have a place in
the treatment of certain central and peripheral nervous disorders as
well. The therapeutic potential suggested by early clinical experiments
and speculation might very well lead to the development of a new
treatment modality--Magnetic NeuroMedicine--with important implications
for pain management.
MAGNETISM is already well established in
medicine as an investigative toll of inarguable importance (magnetic
resonance imaging or MRI). Less well known is the existence of
transcranial magnetic stimulation (TMS). A small circle of
investigators, having made extensive use of TMS as a noninvasive method
of mapping regional brain activity, has been applying it experimentally
to treat such neuropsychiatric disorders as Parkinson's Disease,
clinical depression, migraine, and epilepsy (1). Encouraged by early
results, clinical researchers unflinchingly proclaim that TMS will be a
"neurophyschiatric tool for the 21 St.
century" (1), the hyperbole or prescience of this statement to be
decided in the crucible of clinical reality.
In the AMERICAN JOURNAL OF PAIN MANAGEMENT,
Michael Weintraub, MD, using a less sophisticated technique, provides
further evidence in support of the magnetism's therapeutic potential.
This is a small but impressive pilot study in which patients used
garden variety magnets to treat painful symptoms of peripheral
neuropathies of multiple origins (2). The project was undertaken
because the author was intrigued by the public's embrace of
commercially available magnetic devices for the treatment of sore feet,
a non conventional medicine approach based upon purely anecdotal
reports. But, as the author notes, in 1995, the sales of these devices
amounted to $100-million in the US
and CANADA,
and an estimated 1.2-billion worldwide---an "attractive" venture fueled
by mainstream medicine's continuing neglect of pain.
Nonconventional medicine attracts the desperate and often gullible
sufferers of orphan conditions. Mainstream medicine equates it with
charlatanism and generally dismisses nonconventional methods as unsound
and unproven, all too often without any evidence 'for' or "against". In
this case, the author resisted that reflexive and unscientific
response, and, with a handful of patients and a relatively
straightforward methodology, decided to put magnetism--and, indirectly,
mainstream medicine, to the test. It is fair to say that magnetism may
not be the "antibiotic" of pain medicine, but the surprising and
dramatic outcome justifies the author's conclusion that the "...results
are exciting and encouraging and warrant further investigation..."
which he is undertaking.
Weintraub chose patients with peripheral neuropathies, conditions that
are largely intractable, are usually progressive, and are refractive to
most conventional therapies. Fourteen patients, eight with diabetic
neuropathies (N-DN) were given magnetic foot pad insoles which they
were to wear 24 hours a day for up to four months. The investigator
used a variety of electrophysciology studies, and the patients utilized
visual analogue scales (VAS) twice a day to quantify their pain.
Overall, 64% of the 14 patients showed statistically significant
improvement in the paresthesias of numbness and tingling. DN patients
had the best response of the two groups, with 75% (6/8) improving, 38%
(3/8) completely. The N-DN group had a 50% response rate. VAS scores
reflected the changes in decreased pain.
The most significant finding is that peripheral neuropathies are, for
the most part, responsive to continuous submaximal magnetic stimulation
(CSMS). Additionally, the treatment is relatively inexpensive and has
NO side effects, the most disquieting finding was that the conditions
returned when treatment was discontinued, suggesting that treatment was
symptomatic at best. On balance, however, this therapeutic outcome
differs little from that of most pain management modalities which
usually relieve but do not eliminate the pathology. The most logical
conclusion to be drawn from this small unblinded trial is that CSMS has
therapeutic promise which needs to be rigorously and systematically
explored.
Weintraub credibly speculates on the biological effects of magnetism on
nerve conduction fibers. It is known that the pathophysiology of
dysesthesiae involves the unmyelimated and myelinated small C-fibers.
he theorizes the CSMS selectively recruits C-fibers which, in
neuropathic pain, are inhibited by the large A-delta fibers.
Anticonvulsants are also believed to act on C-fibers by affecting the
voltage-dependent sodium or calcium channels. This raises the question
as to whether combination magnetic-pharmacological treatment in cases
where monotherapy by either method is not effective could be considered
a viable therapeutic option. The attractiveness of combination therapy
is enhanced by the author's speculation that magnetism improves blood
flow. This contributes to a milieu in which opioids and the
proliferation of opoid receptors tend to flourish. It is not a quantum
leap in reasoning to envisage some pain treatments based upon,
"magnetic-pharmacology".
The author uses the term neuro-protective to describe the effects of
CSMA. Whether that was operative in these patients is not clear,
especially if it is meant to imply retardation or prevention of the
disorder's progression. NEURO-PROTECTION is an important concept, and
further research is warranted if for no other reason than to see if
CSMA not only delays progression of peripheral nerve damage but
whether, as in the case of some toxic cancer chemotherapy's, can
prevent it.
Vincristine, for example, is a highly effective chemotherapy for the
treatment of acute lymphocyte leukemia (ALL). But its notorious
peripheral nerve toxicity is the major dose-limiting factor, preventing
more effective treatment. If truly NEURO-PROTECTIVE, CSMS would
dramatically alter ALL therapy.
The public market for magnet devices for painful conditions is robust,
even--or especially--without medicine's tacit approval. Magnetic steel
balls are marketed for arthritis and fibromyalgia. there are even
magnetic mattress pads for sore backs. It is intriguing to think how
much more effectively these conditions might be treated with magnetized
garments (eg, corsets, gloves, neck collars, socks) designed to be worn
all or most of the time--the constant exposure an important condition
the author tells us.
The study is not isolated or idiosyncratic example of magnetism's
possible therapeutic value. It is one of a number of impressive
clinical experiences to demonstrate this force's positive biological
activity (1). TMS, earlier referred to in the experimental treatment of
neurological disorders has been used to stimulate the cerebellar vermis
to demonstrate its function in the control of saccadic eye movements
(3). Could this same laser precision magnetic probe someday become the
magic bullet to the thalamus, the putative storm center of pain? TMS
and magnitised boots may represent the high and low tech cousins,
respectively, of a dynamic force spectrum.
And finally, the development of an electromagnetic approach to provide
pain relief would not only add another treatment modality, but would
help the youthful science and practice of pain management grow by
broadening its armamentarium and horizons. It is a field still riven
with internecine struggles (4-7), with specialties trumpeting
ideologies over science, each claiming exclusivity to a complex
clinical disorder which more often than not, defeats our best efforts.
We grow, and our patients ultimately benefit when we are able to
transcend our petty bickering in favor of the larger issue. Another
treatment option is a welcome addition to the family, and the ability
to embrace, incorporate, and nurture any new idea is a sign of
intellectual and clinical maturity. Let the magnetic force be with us

Introduction
Often having been regarded as 'fringe
medicine' magnetic therapy is gaining increasing attention from the
medical world. Predominantly its use had been in the field of
orthopaedics. This primarily related to the use of magnetic fields to
fracture union .
However, criticism was raised that research lacked rigour and
that controlled, double blind trials were needed to justify the claims
made for its efficacy. There is evidence that this has been
addressed, and a number of papers have been published as a result. For
example, Sharrard has presented the results of a double blind trial
carried out on clinical and radiologically identified cases of
delayed union. The research, carried out at the Royal Hallamshire
hospital, Sheffield, records that
significant results were achieved using pulsed magnetic therapy .
Taking a broader approach to its use in orthopaedics, Trock
was among those investigating the successful application of PMF for the
treatment of osteoarthritis of the knee and cervical spine .
Increasing research began to appear from Japan
in the late 1950's. Interest in magnetic therapy had been encouraged as
it became apparent that it had the potential to be an invaluable tool
in a much wider range of clinical applications. There were a number of
medical congresses on magnetism, with three focusing on magnetic Fields
and living bodies held between 1974 and 1976. Lightwood (1989) referred
to the successful use of pulsed magnetic therapy in the following
instances:
a) circulatory disease of lower limbs
b) oedema
c) bronchial oedema
d) pain relief
e) deep vein thromboses
f) dental pain
Research continues in the U.K, France, China,
Canada,
Japan
and the USA, where
as recently as 1970, the American government began funding new research
at FloridaStateUniversity. In
Eastern bloc countries, the position was different. Studies
have investigated the effect of magnetic fields on a wide range of
conditions including asthma, heart failure and cancers .
These studies show evidence of alleviation of symptoms, particularly
when used in conjunction with other treatment regimes such as drugs and
physical therapy .
Magnetic therapy has been used widely due to its low cost in times of
financial restraint and ease of application at a time of increasing
locomotor disease. Furthermore, the treatment is well tolerated by
patients of all ages .
Changes in political climate have enhanced communication and
dissemination of information, so that details of this research are now
becoming available to the western world. There is a wealth of data now
available and this report can give only a brief outline of the research
undertaken .
Properties of Magnetic Fields
There are 3 types of magnetic field:
a) sinusoidal
b) pulsed
c) static .
All three types have been employed in
carrying out clinical investigations, with a number of studies
comparing the efficacy of static and pulsed fields .
Sinusoidal fields have also been included in trials .
Sinusoidal field
This type of field rises and falls about a
zero point. It is produced by an AC current through a solenoid. In
essence, as the current increases and decreases with each change
in direction of flow, so the field rises and falls, and the polarity
reverses. In actual fact, the field is more related to the shape
of the waveform applied to the coil. The coil modifies the
waveform to generate a field that is not a true sinusoidal field .
Pulsed Magnetic field
This type of field is switched on and off at
a base frequency rate (i.e . 50Hz or 200Hz). It is supplied with
a square waveform signal.(see fig 2a.) Again, the coil modifies the
waveform and gives out a pulsing magnetic field which follows a saw
tooth type pattern.(see fig 2b.) Pulsing of this base frequency at
rates of say 5 to 25 times a second allows the field to be switched on
and off in 'packages'. This pulsing of the base frequency has
differing biological effects depending upon the rate.
Static field
This can emanate from a permanent magnet or
be produced by a coil carrying a D.C. current. The field's intensity
depends on the magnitude of the current through the coil or, in
the case of a permanent magnet, the density of the material and the
degree of alignment of the domains .
Interaction Mechanisms Experiments into medical
applications of magnetic therapy have been shown to include:
a) an analgesic effect
b) resolution of soft tissue damage
c) enhancement of fracture union .
In each case, this is due to interactions
between the magnetic field and tissue at the cellular level. An insight
into these mechanisms was discussed in more detail in a paper published
in the OCPPP journal (Laycock 1996) On the basis of further research it
is now possible to look at this at the sub atomic level .
Three categories of action have been identified.(Jerabek
1996) Firstly, electro-magnetic induction is produced. This is the key
mechanism for interactions between magnetic fields and tissue. This can
be viewed as essentially the same as any electro-magnetic induction
process in that charged particles (cations and anions) are caused to
move by an inducing field thus causing a flow of current. This applies
to both pulsed and static fields, the mechanism for this being relative
movement between field and tissue. This is of greater significance with
a pulsed field than with a static field. (Special consideration of
static fields is given later.) The other two features of
interactions are of lesser importance in considering biological effects
.
a) Specific molecules(diamagnetic and
paramagnetic molecules) may change their orientation due to the applied
field. This effect applies principally to static fields and is of
lesser importance .
b) At the subatomic level, magnetic fields can have an influence
on spin states of electrons .
Measuring Magnetic Field Strength
Tesla - This is the largest unit. This
strength is not commonly used in medicine .
Gauss (1G=10-4 tesla) - A great deal of research is operating in ranges
of 100G or less .
Picotesla (One p = 10-12 T or 10-8G) - This measurement is commonly
used for very low emission devices. Experiments with this strength have
been predominantly in the area of neurology .
Static Fields
Cellular effects of static fields in terms of
induction are principally due to interactions caused by:
a) bodily movement between the static magnet and biological tissue .
b) blood flow- venous, arterial and capillary flow
c) thermal agitation of cells within the area of the applied field
The amount of relative movement in a) and b) are of lower intensity
than those of pulsed fields. In terms of c, the amount of vibration due
to heat is at a microscopic scale, although the frequency may be
higher. If comparison is made between the effect of a pulsed field as
against a static field of similar intensity, the effect of the static
magnet will, therefore, be much lower. It is necessary to have a far
more intense field over a longer period of time for static fields to be
effective .
The initial advantage of a pulsed field is that the frequency can
be pre-set to get the optimum effect for a specific condition by a
combination of base frequency and pulsating frequency. However, static
fields provide a 'fix and forget' form of therapy; static which may be
left on the injury for a prolonged period of time. This allows the
slower interaction to take effect .
The Question of Polarity
The field emanating from a static magnet will
follow the easiest path, flowing from North to South. The actual
magnetic flux does not change in character in its transit. The
difference within the field pattern is that of intensity .
In free space, its density exterior to the magnet itself will be
highest at the poles, the two being equal since what leaves at the
north is exactly equal to that entering at the south. There is no net
outflow from the system, hence the name static .
Where magnetic material is placed exterior to the magnet, but within
the field pattern, the flux will take the easiest path and be distorted
to pass through that material on its way back to the magnet's south
pole. Biological material placed in the field will see different
directions of flow, depending on the orientation of the field at that
point. Thus cellular material will be subjected to a flow in one
direction as the field enters the material, but the reverse as it
leaves. So both polarities will be seen to exist. The argument for
North or South pole having differing effects for different conditions
is difficult to comprehend since the only change in the nature of the
field is its density, regardless of the direction of flow .
A number of claims have been made regarding the different actions of
north versus south poles of magnets in relation to therapy. Some
reports have suggested that the north pole of a magnet has antibiotic
properties, while the south pole has energy giving properties. However,
after consideration of a significant range of scientific reports and
analysis of research presented at the First World Congress in
Magnetotherapy (1996) it was concluded that, with few exceptions, there
was no firm evidence to support the idea that polarity is of specific
significance .
Veterinary Use
The use of magnetic therapy with animals is
accepted by many trainers, animal therapists and some veterinary
surgeons. Here too, its use is primarily to enhance fracture union, for
other orthopaedic problems such as sprains, ligament injuries and
for soft tissue injuries. Magnetic therapy has been recommended over
other methods for relieving a range of equine problems.(Bromley 1993)
It is its effectiveness at enhancing and accelerating the healing
process in this type of injury that has made magnetic therapy so
popular with trainers and owners in the equine and greyhound field .
As in clinical medicine, the idea of using magnetic therapy for
other conditions is less recognised. However, if the equipment is in
the hands of a trained professional, able to select an appropriate
method (pulsed or static), duration of treatment and frequency,
magnetic therapy can help to improve other conditions including
enhancing the absorption of nutrients and improvement of blood flow.
Cases are recorded where magnetic therapy used in conjunction with
other conventional treatments can bring about recovery, whereas
conventional medical treatments alone had been ineffective.(Scott
1995) In the sphere of research, there is a long history of, and
wide range of, animal experimentation. In a number of cases, these
experiments often confirm, in more controlled conditions, the main
effects seen in clinical practice. Such experiments are, however,
more frequently conducted with a view to advancing human medicine
than veterinary medicine, with unfortunate consequences for the
subjects .
Animal experiments constantly prompt the question of whether the
results can with certainty be extrapolated to humans, and vice versa.
There are cases where animals are able to tolerate without adverse
effect some treatments which humans cannot .
Equally there are instances where the reverse is true .
Animal Experiments
Considerable experiments using animals have
been carried out both in the East and in the West. These have made a
vast contribution to research, particularly in aspects which could not
be easily undertaken with human volunteers due to questions of
ethics. Research was also carried out using healthy animals to
help clarify important parameters such as optimum flux density,
frequency and treatment times (Toprotsev and Taranov 1982) Short
duration treatments were therapeutic, while long exposure could have
adverse effects in some instances. They also carried out comparative
experiments with the conclusion that pulsed magnetic fields were the
most effective .
Animal experiments also made significant contributions to
identifying the effects of magnetic fields on biochemistry, immune
responses, infectious diseases, cancer and reproductive functions. The
majority of studies on reproduction showed that there were no adverse
effects. Pafkova (1992) found no higher incidence of mortality or
malformation in chick embryos exposed to MF. However, in one case rats
suffered a higher rate of mortality. The significance of this was
thought to be due to a long exposure at a rate of 90 minutes daily over
a 4 month period .
Despite the fact that it is generally recommended that magnetic
therapy is contra-indicated in cases of cancer, animal research has
been carried out on experimental tumours. Trials indicate that tumours
have been caused to shrink. This effect has been seen both for pulsed
therapy (Zakharyuta 1987) and magnets .
Clinical research
This covers a very wide scope, particularly
with the input from Eastern Europe.
It had been known from the 1940's that magnetic fields were thought to
influence the cellular membrane. This lead to the concept that PEMF
accelerated the re-establishment of normal potentials. (Sansaverino
1980) Warnke suggested that magnetism could cause hyperpolarisation of
synaptic membranes, resulting in pain control. Biochemical reactions,
again at the cellular level, due to magnetic fields could be the
mechanism for enhanced fracture union. (Madronero 1990) Increasing
research has supported these ideas, and has also indicated that
magnetic therapy can bring about an improvement over a wide range of
conditions.
a) Peripheral Vascular Disease
Conditions investigated include oedema, ischaemia and stroke. Oedema
has many causes, and many parts of the body may be affected. Pulsed
magnetic therapy has been shown to reduce oedema. The re- establishment
of normal potentials in the cell helps reduced edema and is therefore
of benefit in many soft tissue injuries .
A comparison of static and sinusoidal fields applied to
atherosclerotic and endarteritis obliterans was carried out by Demetski
and Kartashov. Best results were from sinusoidal fields, up to 66%
improvement was achieved which lasted up to 10 months afterwards. There
was evidence of improved circulation. Static field also produced
improvement of up to 60%. A study of over 3,000 patients was carried
out by Detlavs et al comparing efficacy of static and pulsed fields. A
total of 30 exposures, each of 10 minutes were applied .
Results showed increase in number of capillaries after just a
single treatemt .
Hypocoagulation was also achieved. Other work included Benda and
Dipoldova (1986 - 1990) - effects of MF on ischaemic disorders of limbs
due to diabetes mellttus .
b) Heart disease
Improved blood flow benefits patients suffering from heart disease and
from hypertension. Kirichenko found some improvement in these
conditions. The frequency of angina attacks were reduced by 57% when
patients were given 15 minutes MT on alternate days (Ezhova). In each
of these experiments the total number of treatments was 12 or below .
c) Neurological Diseases
A vast range of conditions can be covered under the heading of
neurology, including migraine, epilepsy and multiple sclerosis and
parkinsons disease .
Valentovna (1987, 1990) used PMT to see if the latter could be
improved. Significant results were achieved with 94% of patients
reporting general improvement. Up to 12 treatments each of 20 minutes
were given at a frequency of 25Hz. MS patients were also treated, but
in this case single exposures of 10 minutes were given to the thorasic
and lumbar spine and to the lower limbs .
While some improvement was noted, most work in the field of MS and
Parkinsons has been carried by Sandyk using picotesla devices .
Some progress has been made in investigating the use of
magnetic therapy to generate nerve growth, although still in its early
stages. It has been found that 20 minutes daily exposure at 2Hz can
stimulate up to 35% increase in neurite growth in culture
(Sisken) More recently, neurite growth in rats has been stimulated
using pulsed magnetic therapy.(Walker) The rats had crushed sciatic
nerves, but after treatment no functional difference was apparent,
however the experiment needs to be repeated on a larger scale to be of
statistical significance .
d) Rheumatoid diseases and orthopaedics
Research into the use of magnetic therapy in fracture repair has
possibly encouraged research into this field more extensively than
others. Both static and pulsed have been used in trials. Pabst et al
found that the use of magnetic foil proved superior to other standard
treatments for minor muscular injuries and secondary tendonyosis, with
statistically significant results achieved in 10 days. In connection
with spinal injuries, pulsed treatment reduced pain and spasm. It was
also noted that PMT did not exhibit any placebo effect.
(Valentova) There is considerable interest in the use of magnetic
therapy to prevent or reverse osteoporosis. Pulsed magnetic therapy
promotes the healing of frctures by stimulating the small
piezo-electric currents which naturally occur in the bone and encourage
the ormation of bone. Tests have shown that bone density can be
increased significantly compared to controls (approx 8% in test group
against 0.8% of controls) (Haas 1993) Patients in both groups were
given 30 treatments of 45 minutes over 8 to 12 weeks supplemented by
vitamins, oestrogen and calcium .
e) Dermatology
Both static and pulsed fields have been applied to treat a range of
skin conditions. Tretyakova found that PMF was superior to conventional
ointment .
Fifty patients with atopic eczema were treated at 50Hz for 10 minutes
daily .
By the end of the experiment all were improved, with 30 being
completely symptom free. The controls treated with conventional
ointments had deteriorated. Pulsed treatment has frequently given
rapid results often after only a couple of treatments. A double blind
trial is now under way to treat leprosy patients. (Coulton)
f) SurgicalImplications Building
on earlier animal experiments, Nikolski applied static fields to
patients immediately after spinal surgery. Most patients had pain
relief within a few days of the operation. The rate of healing
was accelerated, there was less oedema. No complications of infection
occurred, but did in the control group) and as an bonus, there
was a tendency to hypocoagulation. This reduced the risk of deep vein
thrombosis and avoided the need for anticoagulation therapy .
g) Cancer Research with animals has suggested that
regression can occur if treated with magnetic fields. Much of the
research has been carried out using static magnets. Field strengths
used were above 4,000 gauss. Philpott claims that fast growing
melanomas can be reversed, but that constant application over several
months is required using solid state magnets of greater than 2,000 G.
He suggests that as cancers are very vascular, they would have a
reduction of nutrients due to the vaso-constricting effect of the
field. However, clinicians still suggest that treatment is
contra-indicated. Not all research into tumours has been confirmed by
biopsy , and, as a safety measure, if a negative effect has been
observed in even a single experiment then such treatment is considered
inappropriate pending further investigation .
h) Other Areas of Research
Many other medical disciplines are, and have
been, involved in research .
While improvements in the condition have arisen, common features of the
disease process are often present, such as oedema, inflammation
and infection. Time does not allow for detailed information of
each investigation. A mention of some of the areas, such as
gynaecology, burns, opthalmology, immunology and paediatrics gives an
indication of the scale. A world conference is now held on an annual
basis to allow for dissemination of the latest findings, both for and
against .
CONCLUSIONS
Magnetism already plays a significant role in
medicine with the development of MRI scanners now used as a diagnostic
tool. The range and depth of research carried out world
wide justifies its consideration for use in treatment. It is not a cure
all, but can be used to supplement other forms of conventional
treatment, whether this be drug related, surgical intervention or some
form of physical therapy .
Correctly used it can accelerate the healing process. Research
has to be carefully evaluated. Some trials have been too small scale in
scale to be of statistical significance yet merit repetition in
order to confirm or repute their conclusions. While there are still
some experiments carried out which need to be repeated under carefully
controlled conditions, many have been repeated with a sound scientific
approach. Although some results are subjective, based on patient
feedback, many others use clinical tools such as Xray reports and
biopsy to confirm results. For example, Haas confirmed improved
bone density by scans taken pre-trial then at 3, 6 and 12 months .
Main recommendations
Clinicians have determined a number of
important factors to consider, especially in relation to patient safety
.
A.When
selecting the type of equipment to be used to produce the magnetic
field, it is important to consider the strength of the field .
B. Weak fields are therapeutic, very strong fields can cause
damage .
C. Frequency is important. With PMF different frequencies have
different biological effects. For example, pain control requires 200Hz
base frequency.
D. There are two areas to consider: Duration of each treatment
session can be as little as 10 minutes. Ten to fifteen treatments
in total are usually sufficient to bring about an improvement. Cases
not responding after 30 sessions need to be re-evaluated. Inappropriate
frequency may have been used, or the problem may not be appropriate for
this type of therapy. Bone is the exception to the rule, it requires
longer treatment intervals over a longer duration. Fracture
healing may be not be initiated until treatment has been given for a
month .
E. In certain conditions, careful choice should be made in
selecting the area for treatment For example, to treat
thrombophlebitis it is better to expose the complete limb rather than
concentrating treatment purely on the inflamed area. In some
cases ischaemia, the corresponding spinal segment should be
treated as well as local exposure. Guidance should be obtained from a
qualified practitioner .
F. Time varying magnetic fields generally have a better effect
than static, especially in chronic conditions .
G. There is no firm evidence to support claims that the north
pole of a static magnet has greater effect in therapy than a south pole
.
H. Contra-indications. In cases of pregnancy and presence
of tumours, magnetic therapy is not generally recommended, despite the
trials which indicate that no adverse effects arose. ( see above notes)
Trials into treatment of cancer continue and it may be that certain
types of cancer will be appropriate for treatment this way.
Magnet
Therapy: Lifting the Burden of Diabetic Pain
By Dr. Michael Weintraub
Diabetes
affects more than 15 million Americans, and more than half of them
develop diabetic neuropathy as a result. Neuropathy can cause extreme
pain in the feet and limbs, making the slightest movement
excruciating.
But
thanks to Dr. Michael Weintraub, a neurologist at Phelps Memorial
Hospital near New York City, patients who thought they would never feel
better have had success using an experimental treatment – magnet
therapy.
After
just six weeks of wearing magnetic insoles, many patients got relief
from foot pain – some for the first time in their lives. Below
are answers to questions Dr. Weintraub is commonly asked about magnet
therapy.
What
is magnet therapy?
Magnet
therapy is based on the belief that applying magnets to certain parts
of the body can reduce pain and speed healing. Magnets, by
nature, push and pull matter, and some believe this same force can
affect how our bodies heal and sense pain. Although some
preliminary studies suggest that magnet therapy can indeed decrease
pain, just how it works remains unclear.
How
can magnets help diabetic nerve pain? Are they a permanent cure?
This
is not a permanent cure but appears to significantly help the firing
pattern of the peripheral nerve. We need additional studies with
biopsies to see if the therapy encourages nerve cell re-growth.
Will
any magnet work?
The
magnets I use with my patients are commercially available “450-475
gaussian strength” magnets with a two-inch penetration consisting of
multipolar arrays. All magnets are not the same and manufacturers
advertise their products without significant scientific data. We
are currently doing a study testing to see if this very popular design
is effective in relieving pain. Since these are very weak, they
must be worn for 24 hour periods. The earliest improvement was
noted at 14 days, but it did not relieve the pain totally until a few
weeks later. It is unclear if any of the other varieties (i.e.
unipolar, bipolar) will work, since rigorous scientific testing has not
bee done.
Where
do I place them?
There
are different perspectives regarding where on the body magnets should
be placed. Some researchers say it’s best to apply magnets
directly to the painful area, while others believe it’s more effective
to place them on the “trigger-point” of the pain (which could be
another part of the body altogether).
What
are the risks or side effects of magnet therapy?
There
are no know risks, but the use of magnets during pregnancy or while
wearing a pacemaker may be problematic. Likewise, as a precaution
we exclude individuals from magnet therapy if their spouses have a
mechanic device or pump so as to guard against inadvertent contact, etc.
How
do I know if I am a candidate for magnet therapy?
Many
people seem to end up trying magnet therapy as a result of other
unsuccessful experiences with conventional treatments for pain.
Since there don’t seem to be any side effects associated with using
magnets, just about anyone can try them.
Will
my doctor believe this is a legitimate treatment for my pain?
The
therapy is still considered experimental by mainstream medicine, but
this is also a very exciting period and we hope to have the first
definitive trial of permanent magnetic devices completed shortly.
If this is positive, it will represent a paradigm shift in the
treatment and management of diabetic neuropathy and will open up the
door for future trials to see if it can prevent the emergency of foot
ulcers, which produce 100,000 amputations per year, and also see if
wearing these devices prophylactically can prevent the emergence of
diabetic neuropathy.
How
much does magnet therapy cost? Will my insurance pay for it?
Insurance
does not pay for these devices, which are available commercially and
vary in prices, quality, etc. Therapeutic magnets, depending on
what they’re used for, can run anywhere from $25 for small ones to
hundred of dollars for magnet-filled mattress pads and other
products. If you want to spend money on these products, know that
all magnets are not created equal and you should carefully consider
them before making a purchase!
