Electromagnetic Fields (EMF) and
Induction: Basic Considerations
E = V/l = (A/l )dB/dt
For a circular area
E = V/l = (R/2)dB/dtR ~ meters
B ~ Tesla
t ~ seconds
E ~ volts/meter

How Might Electromagnetism Fit In?
Short answer
Almost all aspects of all bodily functions
have an electrical component
Thus there are ample potential
targets for applied EMF

present in normal tissue

“Under the universal microscope disease
organisms such as those of
tuberculosis, cancer, sarcoma,
streptococcus, typhoid, staphylococcus,
leprosy, hoof and mouth disease, and others
may be observed to succumb when exposed
to certain lethal frequencies, co-ordinated with
the particular frequencies peculiar to each
individual organism, and directed upon them
by rays covering a wide range of waves.”

ActiPatch-BioElectronics Corporation
The clinical effectiveness of the product has been well
established. Testing performed at the Bioelectromagnetics
Research Laboratory at the State University of New York has
shown that ActiPatch
Therapy provides an adequate dosage of electromagnetic
energy for the treatment of soft tissue, and that its power at the
skin level is equivalent to that of traditional high-power
devices. The power level is six to nine orders of magnitude
higher than that which is required to show a biological effect. It
also demonstrated that the cumulative effect of continuous
delivery provides greater therapeutic benefit than sporadic
treatments. More information on the testing and clinical
effectiveness of our product can be found at the following web
