Why does NdFeB have demagnetization?

I believe that many people know that Ru Iron Boron, this is a very strong magnet, but recently there will be a lot of people will have demagnetization phenomenon, NdFeB producers to discuss this issue. The demagnetization behavior of NdFeB in high temperature environment depends on its physical structure. The reason why the magnet generates a magnetic field is that the electrons carried by the substance itself rotate around the atom, thus generating a certain magnetic field force and affecting the surrounding affairs. However, under specific 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 orbits, resulting in chaos. At this time, the magnetic field of the magnetic material itself will be disturbed, resulting in demagnetization. Nd-Fe- The temperature of magnet B is about 200 ℃, beyond which demagnetization will occur. Now that you know the reason for the demagnetization of NdFeB magnets, you can solve this problem by prescribing the correct method. First of all, do not put NdFeB magnet products at too high a 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 adaptive structure, not easy to be affected by the environment. NdFeB magnets have good magnetism, excellent quality and absolutely reasonable price. Magnet manufacturers will pay more attention to the performance of magnets and produce more reliable products.
