EnglishFirst, the history of the magnet:
The magnet is not invented, and it is a natural magnetite. The ancient Greeks and the Chinese discovered that there were naturally magnetized stones in the nature, called "Ironstone". This stone can absorb the small pieces of iron sheets, and always point to the same direction after random swing. Early navigators discriminate the direction as their compass in the sea. Early discovery and use of magnets should be Chinese, which is to use magnet production "compass", which is one of China's four inventions.

Second, the components of the magnet
The magnet component is an atom of iron, cobalt, nickel, and the internal structure of the atom is more special, which is a magnetic moment. The magnet can generate a magnetic field with a characteristic of attracting ferromagnetic substances such as iron, nickel, cobalt.

Third, the type of magnet
Shaped magnet: square magnet, tile magnet, shaped magnet, cylindrical magnet, ring magnet, wafer magnet, magnetic rod magnet, magnetometer magnet, attribute magnet: cobalt magnet, NdFe boron magnet (strong magnet) , Ferrite magnet, aluminum nickel cobalt magnet, iron chromium cobalt magnet, industry magnet: magnetic assembly, motor magnet, rubber magnet, plastic magnetic, etc. The magnet is permanent magnet and soft magnet, and the permanent magnet is plus a strong magnetic, and the spin and electron angle moment of the magnetic material are arranged in a fixed direction, and the soft magnet is plus electricity. (It is also a method of plus magnetic force) and other currents to remove soft iron will slowly lose magnetic.

5. Rubber magnet
Rubber magnets are divided into polyuretic and isotropic, and the same sex suction is relatively weak for publicity (refrigerator stickers, car stickers, etc.), decorative gifts, refrigerator magnetic stickers, toys, teaching materials and other scope. The heterogeneous magnet can be used for small motors, sensors , Magnetic adsorption products, etc.
