What are the reasons for demagnetization of strong magnets?

Author:admin   AddTime:2021-10-29

Powerful magnets Powerful magnets require not only a working environment, but also an indoor environment. Compared with ferrite magnets, alnico magnets and samarium cobalt, its magnetic properties greatly exceed other magnets. Neodymium magnets can absorb 640 times their own weight, so neodymium iron boron is often called a powerful magnet by outsiders. Powerful magnets can be magnetized and demagnetized because magnets are more or less magnetic. Sometimes, what is the reason for the demagnetization of powerful magnets?

However, in normal times, we still have to choose the AC demagnetization method, which is better than the high temperature demagnetization method and the vibration demagnetization method, and the demagnetization efficiency is higher. This is the most popular method in industrial production now.

We can draw up certain demagnetization methods according to the different application conditions of powerful magnets.



High temperature demagnetization method: The first operation of the high temperature demagnetization method is to heat the magnet in a high temperature furnace. After high temperature treatment, the strong magnet will be removed. However, during the heating process, the structure of the internal objects of the magnet will occur due to the high temperature. change dramatically.

Therefore, this kind of demagnetization method is generally used for magnets with gaps and withdrawals. The operation of this method is very simple, that is, the vibrating powerful magnet is strong and violent. After the vibration operation, the internal structure of the magnet is changed, and then the physical properties of the magnet are changed. Generally speaking, this demagnetization method has little effect, and only a small amount of demagnetization can be used temporarily.

This demagnetization method is to place the magnet in a space that can generate an AC magnetic field. After being interfered by the AC magnetic field, the internal structure of the magnet will be disturbed, thereby achieving the demagnetization effect. This method is a common demagnetization method.
