Everyone should know that NdFeB (rare earth neodymium) magnets may be Degauss in a high temperature environment, but in a normal temperature environment, NdFeB magnets may also be degauss(demagnetized). What is the situation? Woolen cloth? Let me introduce you to me.
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
NdFeB magnetic material belongs to rare earth permanent magnet material, NdFeB material contains metal neodymium, and metal neodymium and iron are prone to oxidation and rust, so generally NdFeB requires surface electroplating treatment , If it is not plated well, plus the time of use and wear and tear, the electroplating layer on the surface will crack, and the NdFeB magnetic material will also be demagnetized due to oxidation.
The above is the reason why the NdFeB magnetic materials sorted out by Courage Magnet for you are demagnetized at room temperature, I hope to help you!
