|My experiments with the effects of low frequency magnetic fields on
humans began in July, 2000. I'm a retired engineer, and I had a few large
Neodyium-Iron-Boron magnets left over from an abandoned project. They were almost a cubic
inch in size, and I became curious if the magnetic field could have an effect on the brain
and mind. I tried holding one close to my head, but nothing happened. So I attached it to
a hand-cranked drill and spun it at a fairly fast speed. Sure enough, I thought I felt
something - a kind of spacey or high feeling.
Next, I mounted the magnet on ball
bearings so I could spin it to a high speed and let it slowly coast to a stop. This proved
very effective, and elicited a pleasant, relaxed sensation that was quite enjoyable. The
feeling wore off after an hour or so, and there were no aftereffects. I started doing it a
From there, I designed a professional quality device and built about a dozen, most of
which I sold on eBay. After that I built many more experimental devices, some of them
electrically powered and one that was controlled by a computer.
All along, I had assumed the effect on the mind was caused by eddy currents generated
in the brain by the rotating magnetic field. At 30 Hz and close to the head, the induced
voltage approached 100 mV/m. However, the electrically driven devices were effective up to
10 feet away at 5 to 8 Hz. At that distance, the induced voltage was only a few uV/m, far
below the noise floor of the nervous system. Something didn't make sense.
It was known that many animals could navigate by the Earth's magnetic field, and the
mechanism most likely involved magnetite particles embedded within specialized cells. I
wondered if humans might have a similar mechanism that was capable of sensing rotation,
but not direction.
To find out, I designed and built the experiment documented on this website.
