Analysis of high temperature demagnetization phenomenon of NdFeB magnetic material and solution

Analysis of high temperature demagnetization phenomenon of NdFeB magnetic material and solution.NdFeB, also known as NdFeB magnet, is the strongest magnetic material in the commercial market, and is also called "King of Magnet" by magnet manufacturers. NdFeB magnet is a permanent magnet, theoretically, the magnetism is permanent, but NdFeB products will demagnetize in high temperature environment. What are the solutions for high temperature demagnetization? The following is a small part of NdFeB manufacturer to take you to understand.SourceRare earth magnet-https://www.rare-earthmagnet.com/demagnetization-of-ndfeb-magnetic-material/

Neodymium magnet will produce demagnetization in high temperature environment, it depends on its own physical structure. Ordinary magnets produce magnetic field, this is because the electrons carried by the material itself rotate around the atom in a certain direction, thus producing a certain magnetic force, which affects the surrounding things. But the electrons around the atom in a certain direction also have a certain temperature condition, different magnetic materials can withstand different temperatures, in the case of high temperature, the electrons will deviate from the original trajectory, chaotic phenomenon, the magnetic material in this time the local magnetic field will be disrupted, and demagnetization.SourceRare earth magnet-https://www.rare-earthmagnet.com/demagnetization-of-ndfeb-magnetic-material/

The maximum working temperature of NdFeB magnetic material is about 220 degrees, more than 200 degrees, demagnetization will occur, the higher the temperature, the more serious the demagnetization phenomenon.SourceRare earth magnet-https://www.rare-earthmagnet.com/demagnetization-of-ndfeb-magnetic-material/

First, pay attention to the environment, don't put the NdFeB magnets in the high temperature working environment. The ambient temperature should not exceed 200 degrees, and try to be lower than the critical point of its working temperature.SourceRare earth magnet-https://www.rare-earthmagnet.com/demagnetization-of-ndfeb-magnetic-material/

Secondly, it is technically to improve the performance of products using NdFeB permanent magnets, so that they can have more temperature structure and not easy to be affected by the environment.SourceRare earth magnet-https://www.rare-earthmagnet.com/demagnetization-of-ndfeb-magnetic-material/

Third, you can choose the same magnetic energy product material with high coercivity material.SourceRare earth magnet-https://www.rare-earthmagnet.com/demagnetization-of-ndfeb-magnetic-material/
