Neodymium magnets will be demagnetized at high temperatures, depending on their physical structure. Ordinary magnets produce a magnetic field because electrons carried by the material themselves rotate around atoms in a certain direction, creating a magnetic force that affects things around them. However, the electrons around the atom also have certain temperature conditions in accordance with the given direction, and different magnetic materials can withstand different temperatures. In the case of too high temperature, the electrons will deviate from the original track, resulting in chaos, and the local magnetic field of magnetic materials will be disrupted and degaussed.
The highest working temperature of NdFeB magnetic material is about 220 degrees, more than 200 degrees will appear demagnetization phenomenon, the higher the temperature, the more serious the demagnetization phenomenon.
NdFeB magnet high temperature demagnetization solution:
1. Pay attention to the use of the environment, do not put neodymium magnet products in high temperature working environment. The ambient temperature should not exceed 200 degrees, and should be lower than the critical point of its operating temperature.
2. From the technical point of view, improve the product performance of the use of NdFeB permanent magnet, so that it can have more temperature structure, not easy to be affected by the environment.
3. You can choose the same magnetic energy product material with high coercivity.
