Magnet component is iron, cobalt, nickel and other atoms, the internal structure of the atom is more special, itself has a magnetic moment.
Magnet type: shape magnet: square shaped magnets, magnet, tile shaped magnets, cylindrical magnet, ring magnets, wafer magnets, magnet bar magnets, magnetic frame, magnet: attribute class samarium cobalt magnet, ndfeb magnet, ferrite magnets, alnico magnets, iron, chromium cobalt magnet industry class magnet: magnets, magnetic components, motor, powerful magnets, magnetic, and so on rubber magnet type.
Magnet permanent magnet with soft iron, permanent magnet is coupled with strong magnetic, make the spin of magnetic materials and electronic angular momentum into fixed direction arrangement, soft magnetic is combined with current (
Is also a kind of combined with magnetic method)
Such as current remove soft magnetic iron will slowly lost.
People didn't invent the magnet, is a natural magnetite.
Nuclear magnetic resonance (NMR) diet: a magnet taste salty, flat;
