Many magnet manufacturers will often encounter such situation: the demagnetization of strong neodymium magnets. Why the magnets will need demagnetization? There are lots of reasons. For example, magnet salesmen didn’t understand the actual requirement of customers, customers need the un-magnetized magnets, but salesmen sent the magnetized magnets to customers. The electroplating factory plated the magnets with Zinc, but customers couldn’t accept it because the magnets should have required nickel plated. We will need to demagnetized the magnets if plate the magnets again. There are many other situations. So what are the differences between magnets that have been demagnetized and magnets that haven’t been demagnetized? Many people will care about this matter.
The magnetic molecular structure will have obvious changes occur after demagnetizing the magnets, which will weaken the magnetism of magnets, compared with the ordinary magnets. And after repeated magnetization, the magnetism of magnets will become weaker and weaker. So when we use the magnets that have been demagnetized cannot be magnetized repeatedly, otherwise the magnetism of these magnets cannot meet the use requirement.
The original neodymium magnets which have not undergone high temperature demagnetization, the magnetic structure molecules have not changed, and the magnetic properties are relatively stable. But those magnets need to avoid high temperature, because high temperature will change the molecular structure of the magnet.
To sum up, do you know the differences between magnets that have been demagnetized and original magnets? If you still don’t understand or have any questions, please contact and consult with the manufacturer China Rare Earth Magnet Limited.
