NdFeB magnet is a kind of rare earth permanent magnet with small volume and high magnetic energy product, which is easy to be oxidized and magnetized in the production process. Due to the need to demagnetize and repair during demagnetization, the current demagnetization, hot bath demagnetization an ...

Rare Earth (RE) is a group of 17 metal elements formed by Group III (SC, Y) and lanthanum (La-Lu). Rare earth elements are usually divided into two groups, namely cerium group (light rare earth) and yttrium group (heavy rare earth). Rare earth elements show very similar properties, that is, they ge ...
