Magnets are made of iron, cobalt, nickel and other atoms. Atoms have special structures inside them, and magnets have magnetic moments. A magnet can generate a magnetic field and has the properties of attracting ferromagnetic materials such as iron, nickel and cobalt.
Shape: block magnet, tile magnet, special magnet, cylindrical magnet, ring magnet, disk magnet, magnetic bar magnet, magnetic frame magnet.
Properties: Samarium cobalt magnets, neodymium magnets (strong magnets), ferrite magnets, aluminum nickel cobalt magnets, iron chromium cobalt magnets, industrial magnets: magnetic components, motor magnets, rubber magnets, plastic magnets, etc.
Magnets are divided into permanent magnets and soft magnets. The permanent magnet is strongly magnetized so that the spin of the magnetic material and the angular momentum of the electrons are aligned in a fixed direction, while the soft magnet is energized. (It's also a way to increase magnetism.) When removed by an electric current, soft iron slowly loses its magnetism.
1. Ndfeb permanent magnet is a kind of modern permanent magnet with strong magnetism and wide application.
Mainly used in electroacoustic, permanent magnet motor, communication, automotive electronics, magnetic machinery, aerospace, computer, household appliances, medical instruments, office automation, toys, packaging boxes, leather goods, magnetic accessories and other fields.
2. Permanent magnet ferrites are used as permanent magnets in electric meters, generators, telephones, loudspeakers, television and microwave equipment, voice recorders, pickups and speakers, the magnetic cores of various instruments, and electronic equipment such as radar, communications, navigation and telemetry.
3. Samarium cobalt magnets can work at 300 degrees and have corrosion resistance and oxidation resistance. At present, it has been widely used in detector, generator, radar, instruments and other precision science and technology fields.
4. Aluminum nickel cobalt magnet is resistant to high temperature and corrosion. Mainly used in motors, sensors, medical instruments, hand tools, loudspeakers and various instruments.
5. Rubber magnets have the same sex and the opposite sex. Weak attraction, mainly used for publicity (refrigerator stickers, car stickers, etc.) .). .). , decorative gifts, refrigerator stickers, toys, teaching materials, etc. Heterogeneous magnets have strong forces and can be used in small motors, sensors, magnetic adsorption products, etc.
It is important for businesses to know what different magnets are used for. The product performance can be improved by making full use of the characteristics of different magnets.
