Why does NdFeb appear demagnetization problem

- Jun 04, 2020-

I'm sure many of you know your ferroboron, which is a very strong magnet, but recently a lot of people have the phenomenon of demagnetization, NdFeb producers to discuss this issue.


The demagnetization behavior of NdFeB in a high-temperature environment depends on its physical structure. Magnets produce magnetic fields because electrons carried by matter spin around atoms, exerting a magnetic force that affects everything around them. However, under certain temperature conditions, the rotation of electrons around atoms in a given direction is also limited. Different permanent magnets can withstand different temperatures. When the temperature is too high, electrons will deviate from their original orbit, causing chaos. At this point, the magnetic field of the magnetic material itself will be disturbed, resulting in demagnetization. The temperature of the NdFeB magnet is about 200℃, beyond which demagnetization will occur.


NdFeB Magnet


Now that you know the reason why NdFeB magnets demagnetize, you can solve the problem by specifying the correct method. First of all, do not put the NdFeb magnet under high temperature, pay special attention to its critical temperature, timely adjust its working environment temperature, can minimize the occurrence of demagnetization phenomenon. Secondly, from the beginning of the technology, improve the performance of the product, so that it has more temperature adaptability structure, not easy to be affected by the environment.


Ndfeb magnet has good magnetism, excellent quality, and reasonable price. Magnet manufacturers will pay more attention to the performance of magnets and produce more reliable products.
