Magnets are made of iron, cobalt, nickel and other atoms. The internal structure of an atom is so special that a magnet has a magnetic moment. A magnet can generate a magnetic field and has the property of attracting ferromagnetic materials such as iron, nickel and cobalt.
Shape magnets: block magnets, tile magnets, special magnets, cylindrical magnets, ring magnets, disk magnets, magnetic bar magnets and magnetic frame magnets.
Attribute magnets: 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. A permanent magnet is strongly magnetized so that the spin of a magnetic substance and the angular momentum of an electron are aligned in a fixed direction, while a soft magnet is energized. (Also a way to increase magnetism.) When removed by an electric current, soft iron slowly loses its magnetism.
1. Ndfeb permanent magnet is a 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, televisions and microwave equipment; permanent magnets in voice recorders, pickups and loudspeakers; permanent magnets in the magnetic cores of various instruments; and permanent magnets in electronic equipment such as radar, communications, navigation and telemetry.
3. The samarium cobalt magnet can work at 300 degrees Celsius and has 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 are of the same sex and opposite sex. Less attractive, 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's 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.
