Headset with magnet

Hello people,

I am a student and I have heard rumors of people cheating with a headset,a magnet in their ear , and a induction coil around their necks. Nothing new, but I have heard of someone who has this kind of headset built in such a way that he has his induction coil around his waist. Do you think that can be done? How?

I do not intend to build it for cheating.

Can't see any point in such an arrangement, since any self-respecting examination authority would insist on no headsets being worn.

Yes. Make the induction loop diameter => waist measurement .
As for the magnet in the ear, IMO that's either an urban myth or a con.

This is what I am talking about, but the neckloop will actually be a "waistloop"
My question is, if make it the neckloop as a waist loop, will it "transport" signal to the magnet?
