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.
[G. magnēs]
An iron-based mass or bar with magnetic polarity

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...

This is resulting in fluctuating supply and soaring prices of rare-earth magnets, which is the primary reason why end-users are focusing on reducing their dependency on rare-earth magnets and moving to amorphous iron as a magnetic material, thereby boosting growth of the amorphous iron market.
"The difficult part," says Junzhang Ma, postdoctoral researcher at PSI and first author of the new study, "was to identify a suitable magnetic material in which to look for these Weyl fermions." For years, although the accepted theoretical assumption had been that in certain magnetic materials Weyl fermions could exist by themselves, experimental proof of this was still missing despite considerable effort from several research groups worldwide.
and Fujitsu Limited today announced the development of technology that can automate the design of magnetic material geometries, using AI to minimize energy loss.
