I came across this article on gizmodo. It tells about implanting rare earth magnets to your body and then sense the presense of EM fields through the
oscillation of the magnets. Gizmodo
Interesting info., OP! I must admit that as soon as I saw the title of this thread, this scene from Mean Girls flashed in my mind. I must have a
'fifth' sense too. J/K
I'm very sensitive to energy fields as it is but I can see potential in this. Perhaps for helping vision impaired? Would have to be careful though
because magnets can wipe computer memory.. and most electrical devices have computer chips these days.
I think it was said in the comments section that they're not strong enough to cause damage. One really cool thing you can do is pick up which wires
are flowing with electricity for example. My mother is almost totally blind, I'll have to ask if she'd like these. I doubt it because she has very
sensitive finger tips for reading braille.
