Magnet demagnetization

Will demagnetization occur below the max working temperature of the magnet?

In practical applications, selecting a magnet based solely on the maximum operating temperature often creates potential risks. This is because whether a magnet undergoes irreversible demagnetization depends not only on temperature but is also closely related to factors such as the operating point (load line),...

Causes of Degauss of Nd-Fe-B at normal temperature

When the NdFeB magnetic material is severely impacted, it may be degauss. Why is this? Because the NdFeB magnet will be subjected to violent external force when it is hit, it may cause changes in its internal structure. Does not show magnetism to the outside...
