What are the physiological effects of magnetic field in human beings?

Question

good effects, or bad effects to human's health

Answer 1

None whatsoever.

You know how a compass works? It works because the entire planet is surrounded by an unimaginably large magnetic field.

In order for a magnet to affect your health it would have to be strong enough to suck the iron out of your blood. And you'd probably die from that.

Answer 2

Nothing can happen physically.  We aren't metal.  Our iron content in the blood is so low that it would have to be an extremely powerful magnet to do anything.
