Precautions for Powerful Magnets

Sep. 22, 2020

Neodymium-iron-boron Rare Earth Magnet The third generation of rare-earth magnet-neodymium-iron-boron is the most powerful permanent magnet among contemporary magnets. As one of the most important application fields of rare earth materials, it is one of the important basic materials supporting the modern electronic information industry and is closely related to people's lives.

Ndfeb Magnet is contemporary permanent magnet material with the strongest magnetism and the best performance-to-price ratio. It not only has the characteristics of high remanence, high coercivity, high energy product, high performance and price ratio, but also easy to process into various sizes. Therefore, NdFeB is widely used in aviation, aerospace, electronics, electroacoustics, electromechanics, instruments, meters, medical technology, magnetic resonance imaging, magnetic levitation and magnetic sealing and other devices and equipment that require permanent magnetic fields; especially suitable for Develop various replacement products with high performance, miniaturization and light weight.

Strong Magnets should ensure that the workplace is clean during use, otherwise small magnetic particles such as iron filings will be easily absorbed and affect the use. The characteristics of NdFeB material are hard and brittle, and the suction power can reach more than 600 times of its own weight, and it is very easy to attract and damage. In the operation process, attention should be paid to avoid collision damage for small specifications, and personal safety and protection should be paid more attention to large specifications.

When storing powerful magnets, keep the room ventilated and dry, otherwise the damp environment will easily cause the magnets to rust. The ambient temperature should not exceed the maximum operating temperature of the magnet. Unplated products can be properly oiled to prevent rust when stored. Magnetized products should be stored away from magnetic disks, magnetic cards, tapes, computer monitors, watches and other objects that are sensitive to magnetic fields. The material of the magnet is relatively fragile. During transportation, electroplating (coating), and installation, ensure that the magnet is not subject to severe impact. If the method is improper, it may cause damage and cracking of the magnet. The magnet should be shielded when transported in a magnetized state, especially in aviation Transport must be completely shielded.
