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. 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...

In the late eighteenth century, Franz Anton Mesmer used bar magnets and hypnotic "animal magnetism" (mesmerization) to treat patients.
Take the meter stick and move the bar magnet over the metal objects on the floor.
Designed for applications where clamping is not possible, the adapter tip consists of a powerful bar magnet sandwiched between two steel poles to provide strong adhesion.

Three years earlier, Ampere (see 1820) had shown that a wire helix (or solenoid, from a Greek word meaning "pipelike," because such a helix looks like a pipe with its walls made of turns of wire) acts like a bar magnet when electricity flows through the wires.
In a traditional bar magnet (right), the magnetic field juts out from the north pole and bends toward the south pole.
Unlike the magnetic pole, which is where magnetic needles become vertical, the geomagnetic pole is the intersection of Earth's surface with the imaginary bar magnet the geomagnetic, not the magnetic, pole that controls the aurora.
The motor is similar in principle to the giant electromagnets used in scrapyards to lift cars, in which a powerful permanent magnet (one that, like an ordinary bar magnet, requires no power) is paired with a weaker magnet (one whose magnetic field direction can be flipped by an electric current in a coil).
