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. 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...

Soft magnetic materials with high Fe content, which feature nanoheteromorphous self-organizing structure, are being increasingly employed in electrical transport, as an effective means to reduce worldwide electricity consumption.
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.
With this technology, it has become possible to accurately compute the distribution of eddy currents(1) that flow through an inductor by formularizing the dielectric effects of ferrite microstructures, which are the main magnetic materials used as inductor materials.
These magnetic memories and logic devices put additional constraints on the magnetic materials, where data is stored and computed, compared to traditional hard disk media magnetic materials.
