Based on that study, done at the vet school at TAMU, I calculated, based on the clinical observations, that the minimum threshold for effectiveness was on the order of 100-200 kG/s. NOT just Gauss, not frequency, but the time rate of change of the magnetic field (G/s). This allows you to calculate the minimum induced electrical field “E” based on Faraday’s law of induction, and cellular-level anatomical geometry. These numbers are no secret, I have published them many times, including several times on YouTube videos.
Most people at this point are probably thinking “Gee whiz, that’s too sciency, just tell us the Gauss or the magical healing frequency.”
Nope, sorry, the calculations I did are real science, it involves real math, incomplete and sometimes forgotten physiological measurements, and some very difficult concepts from classical physics. That’s why this technology is not for everyone. But that is exactly how I first estimated the “threshold for effectiveness”.
It’s kind of funny to me, because I have been telling people for years exactly how this all works (at least, what I have found after 20+ years of seriously working on this problem), and yet some people refuse to believe it. Today one of my close colleagues sent me a copy of an email from a new company that is trying to pirate and sell a “new” PEMF product. Obviously, I was not meant to see this email, but…
Triumphantly, one of them wrote “I read Bob Dennis’ stuff today, and he is completely wrong. Induction only works for sine waves!!!”. Then he went on to describe his “new” theories of how PEMF works, based on zero science, zero data, and no understanding of biology. It’s so funny, because I lay the whole thing out for everyone.
So, head’s up ya’ll. Another great “new” PEMF technology is about to be unveiled. Evidently it will be a sine wave, which has been known for decades to have very little or no biological effect. But they will undoubtedly tell you anything you want to hear, so long as you are willing to write a check.
But not me. I am a grumpy old scientist who spent a few decades and bothered to learn a few fields of the hard sciences, and run a few real experiments. And those were my measurements and calculations.
