How to solve the phenomenon of high temperature demagnetization of ndfeb magnet

Many customers in the use of neodymium(NDFEB)  magnets have a lot of questions, which neodymium(NDFEB） magnets in the high temperature environment demagnetization phenomenon has been concerned.

 Why does ndfeb magnet demagnetize at high temperature?

Neodymium magnet can produce demagnetization phenomenon in high temperature environment, this is determined by its own physical structure.Ordinary magnets can produce a magnetic field because the electrons carried by the material themselves rotate around the atom in a certain direction, thus generating a certain magnetic field force, and thereby affecting the surrounding affairs.But electrons around the atoms in accordance with the established direction also has a certain temperature conditions, different magnetic material can withstand temperature is different, in the case of too high temperature, the electronic will deviate from the original track, chaotic phenomenon, magnetic material at this time the local magnetic field will be upset, and demagnetization.

And the resistance temperature of neodymium magnet is about two hundred degrees, that is, more than two hundred degrees will appear demagnetization phenomenon, if the temperature is higher, demagnetization phenomenon is more serious.

Ndfeb magnet high temperature demagnetization of the most effective several solutions

一, do not put the neodymium iron boron magnet products in too high temperature, especially to pay attention to its critical temperature, that is, two hundred degrees, timely adjust its working environment temperature, can reduce demagnetization phenomenon as far as possible.

二, is from the technology, improve the use of the product performance of ndfeb magnet, so that it can have a more temperature structure, not easy to be affected by the environment.

三, can also choose the same magnetic energy product of high coercivity material, if not that only sacrifice a little magnetic energy product, find the magnetic energy product of a little lower higher coercivity magnetic material
