Three environmental factors affect function of high temperature resistant magnet

Three environmental factors affect function of high temperature resistant magnet Environment temperature. Since sintered NdFeB has a negative temperature coefficient (αBr<-0.13%/°C, αHcj<-0.6%/°C), the instantaneous maximum temperature and the continued maximum temperature of the operating environment will cause different degrees of demagnetization of the magnet itself. Contains reversible and irreversible, rehabilitative and non-recoverable. Environment humidity. NdFeB [...]
