magnet

 [mag´net]
an object having polarity (oppositely charged ends) and capable of attracting iron.

mag·net

(mag'net),
1. A body that has the property of attracting particles of iron, cobalt, nickel, or various other metallic alloys and that, when freely suspended, tends to assume a definite direction between the magnetic poles of the Earth (magnetic polarity).
2. A bar or horseshoe-shaped piece of iron or steel that has been made magnetic by contact with another magnet or, as in an electromagnet, by passage of electric current around a metallic (iron) core.
3. An electromagnet built in a cylindrical configuration to accommodate a patient in its core, for magnetic resonance imaging.

Q. who much cost the resonance magnetic machine? new or used

A. here is a company that you can even get a MRI scanner in a leasing program:

Q. hey guys! has anyone ever tried a chinese magnet to help a diet?? Somwone I know who is a chinse medicine healer, gave me a special magnet you stick to the right thumb of your hand to help evoid snack attacks. Did you ever hear anything about it?? did iot help anyone??

A. i tried magnets. not to dieting but magnets to the feet. supposed to help in giving energy while walking (i hike a lot). couldn't say i felt a big difference, but i only tried it for a day- so i don't know...
