Please explain magnetic system and its effect on human body?

Answer 1

A magnetic field will only influence another magnetic field or the flow of electricity (which go hand-in-hand). The only major source of electrical activity in humans is the brain.

So although wearing a little magnetic bracelet is essentially worthless, there are medical uses for magnetism on the brain. Specifically, see http://en.wikipedia.org/wiki/Repetitive_transcranial_magnetic_stimulation .

Answer 2

Magnets ave no effect on the human body. Magnetotherapy is CRAP.
