How to prevent the demagnetization of NdFeB magnets


NdFeB causes demagnetization in high temperature environments, which is determined by its physical structure. The reason why a magnet can generate a magnetic field is because the electrons carried by the substance itself rotate around the atom in a certain direction, thereby generating a certain magnetic field force, thereby affecting related matters in the periphery. However, there are certain temperature conditions for electrons to rotate around an atom in a given direction. Different permanent magnet materials can withstand different temperatures. In the case of too high temperature, electrons will deviate from the original orbit and cause chaos. At this time, the magnetic field of the magnetic substance itself is disturbed, and demagnetization occurs. The temperature of the neodymium iron boron magnet is about 200 degrees Celsius, that is, if the degree exceeds the degree, demagnetization will occur.


Since everyone knows the reason for the demagnetization of NdFeB magnets,

It is possible to solve the problem with the right medicine:

First, do not put the NdFeB magnet product in too high temperature, especially pay attention to its critical temperature, adjust its working environment temperature in time, can minimize the phenomenon of demagnetization.

Second, starting from the technology, improve the performance of the product, so that it can have a more temperature-dependent structure, not easily affected by the environment.
