[Biophysics] Influence of magnetic fields on human body

[Ron]

Hi,

I am looking for information on the influnce of low frequency magnetic
fields on the human body.

Low frequency means in this case pulsating magnetic fields with a frequency
of 0-3 Hz modulated with another frequency of 10-50 Hz. My current circuit
doesn't match these figures, but that's what I had in thought.

I personally have clear sensations in hands, arms and belly when exposed to
such fields. Call it an itching feeling.

The force must be relatively strong, while I am using 2-3 A at 12 V. So,
basically, 20-30 W of electrical power is used in the coil. The effciency I
don't know, but my compas reacts from an arm's length.

My question is whether or not exposure to such fields could cause adverse
effects, and if so what? Or could such fields used for magnetic therapies?
Through which mechanism is it possible that I have undeniable sensations
when exposed to such fields.

Googling didn't yield much useful information yet. Hopefully anyone here has
something useful.

Thanks on beforehand.
