Rare earth or perpetual are made from components in the rare earth assembly of the occasional table of the components. While once acknowledged rare, these components have been discovered to be as normal as lead or tin. Be that as it may, their helpfulness in changeless did not get clear until the Rare earth was

High Temperature Resistance Magnets
Three environmental factors affecting the function of high-temperature magnet Ambient temperature Because the sintered NdFeB has a negative temperature coefficient （αBr<-0.13%/℃，αHcj<-0.6%/℃）, the highest instantaneous temperature and the continuation of the highest temperature will demagnetize the magnet to varying degrees, including reversible and non-reversible, recoverable and non-recoverable. Ambient humidity Neodymium is easy to corrode and oxidize.
