Dongguan magnet effect 】
Magnet component is iron, cobalt, nickel and other atoms, the internal structure of the atom is special, itself has a magnetic moment.
Magnet varieties: 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: magnetic components, motor magnets, rubber magnet, powerful magnets, magnetic, and so on.
Permanent magnets and magnetic magnet points, and 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 gradually lost.
Can produce magnet magnetic field, has attract ferromagnetic materials such as iron, nickel, cobalt and other metallic properties.
The halfway point of the bar magnet with thread hanging up, still, it will ends of each point to the south and the north earth, pointing to the north called refers to the North Pole or at the end of the N pole, pointing to the south is refers to the South Pole or at the end of the S pole.
If the earth as a big magnet, the earth's magnetic North Pole is to point to the South Pole, pole is magnetic.
Between the magnets and magnets, magnetic pole with the same phase exclusion, synonym poles attract.
Mutually exclusive, so, the compass and the South Pole ones and the arctic are exclusive, while the compass and the ones to attract.
Classification: the magnet can be divided into & other;
A permanent magnet & throughout;
With & other;
The permanent magnet & throughout;
Permanent magnets can be so natural products, also called lodestone, can also be made by human.
The permanent magnet, such as the electromagnet, present magnetic only under certain conditions.
Strong magnets, magnets, magnet, magnet, ndfeb magnet, rare earth permanent magnets
