When choosing the magnetizing power supply, we need to decide which specification and performance of magnetizing equipment to choose according to the specific situation of magnetic materials. The main reference parameters are as follows: 1. Magnetic material (the manufacturer of magnetic material can provide relevant data) 2. Magnet size and shape 3. Are there any special requirements for the waveform of magnetic field or flux 4. Is the magnet separate or assembled 5. Number of poles 6. Saturation magnetization or quantitative magnetization 7. Production conditions and nature, whether it is used for assembly line and production efficiency

Environmental temperature. The sintered NdFeB has negative temperature coefficient (alpha Br<-0.13%/ alpha Hcj<-0.6%/ C, c), so the use of instant maximum temperature environment and sustained the highest temperature will produce different degrees of magnet demagnetization, including reversible and irreversible, recoverable and unrecoverable. Environmental humidity. NdFeB itself is easy to corrosion and oxidation. In general, we use surface treatment to protect permanent magnets, but it can not fundamentally solve the influence of ambient humidity on the magnet. The drier the environment, the longer the magnet will last. How to measure the magnetic performance? There are three main parameters: Br (Residual Induction), remanence Gauss, is a measure of the magnet foreign can provide magnetic field parameters; the coercivity of Hc (Coercive Force), Oersteds, is a measure of resistance to demagnetization parameters; energy product of BHmax, Gauss-Oersteds, is a physical quantity characterized by energy storage how much energy.
