The magnetic field strength of a strong magnet is also related to the magnetization direction, service temperature and volume of the material. NdFeB is mainly composed of iron, cobalt, nickel and other substances, which can obtain high magnetism after being magnetized at room temperature, and can still maintain strong magnetism after removing the external magnetic field. Ferromagnetic materials have strong magnetism, mainly because of their strong internal exchange magnetic field.

Neodymium magnet material with N35-N52 characteristics. Under the same size, the finished products made of different materials have different magnetism, and the higher the grade, the greater the magnetism. The magnetism of the magnet is also related to the service temperature of the product. The maximum high temperature resistance of ordinary magnets is 80℃. When the temperature exceeds 80℃, the magnetism of the magnet will gradually weaken and lose its magnetism. Different NdFeB materials can meet different requirements of high temperature resistance. Neodymium magnets can resist high temperature up to 230℃, so neodymium magnets are now suitable for various industries. The magnetism of a magnet is also related to its volume. In the case of the same material, the magnetic strength is different with different product sizes.

All these directly affect the magnetism of the finished magnet. Therefore, customers can choose magnets with different materials and sizes according to the requirements of products when purchasing. Shenzhen aier magnetoelectric
