Field Intensity (also known as amplitude or flux density) is a quantitative description of an electromagnetic field that depends on current flow and direction. Electromagnetic intensity is described as flux (or flow) density and has been given the unit Tesla (T), after Nikola Tesla, a Serbian born American scientist who is best known for many revolutionary contributions in the field of electricity and magnetism in the late 19th and early 20th centuries.
The determinants of field intensity (amplitude) are the magnetic coil length (meters), the number of turns (or "windings") of the coil, and the strength of the electrical current (Ampères) applied to the coil. Together with the induction constant and the specific resistance of the material, the field intensity (or flux density) of a magnetic field can be calculated.
Diagnostic systems such as the magnetic resonance imaging (MRI) use field strengths in the Tesla range (1.5 – 3 T). The range of units has been shown below:
- 1 T = 1 000 mT (milli-Tesla)
- 1 mT = 1 000 microT (micro-Tesla)
- 1 microT = 1 000 nT (nano-Tesla)
- 1 nT = 1 000 pT (pico-Tesla)
"Gauss" is a unit of flux density still used in some parts of the world. 1 Gauss = 100 mT. The electromagnetic applications used by the iMRS are at field strengths 10,000 to 1,000,000 times weaker than fields applied in FDA-approved transcranial magnetic stimulation systems and diagnostic magnetic resonance imaging (MRI) systems.
The iMRS uses extremely low field strengths. Since the target of signaling is the cell membrane, extremely low field strengths are quite adequate in producing a beneficial biological response.
This is the principle of the "biological windows," a concept developed by Dr. Ross Adey. Dr. Adey discovered that there are a range of electromagnetic frequencies to which the body responds more readily. This principle can likewise be applied to field intensity -- there is a "biological window" of electromagnetic intensities to which the human body responds best for wellness, stress reduction, enhanced oxygen delivery and overall health. The research of Goodman and Blank proved the principle of the biological window in relation to electromagnetic field intensity. They found that human cells most readily express a cell-preserving gene, heat shock protein 70 (hsp70), at 7-8 microTesla rather than a stronger field intensity above 70 microTesla.
The native language of the human cell, from an electromagnetic perspective, is a subtle whisper.
All iMRS systems are designed with this native language in mind, and use extremely low field intensities that communicate most effectively with the cell membrane. The result is the best possible wellness effect for all 75 trillion cells of the body.
