Magnetization method:
1, constant current magnetization (low-voltage large-capacity capacitive discharge), suitable for magnets with low coercivity, such as ferrite magnets, such as NdFeb magnets.
2, pulse magnetization (high voltage small capacity capacitance discharge), suitable for magnets with high coercivity, such as ferrite magnets.
Magnetization principle:
1, the working principle of constant current magnetizer: through constant current direct current in the coil, the coil produces a constant magnetic field. Suitable for magnetization of low coercive permanent magnet materials.
2, the working principle of the pulse magnetizer: through the instant pulse current in the coil, the coil produces a short super strong magnetic field. Suitable for high coercive permanent magnet materials or complex multi-pole magnetization occasions.
After the magnetism of the magnet is lost, it is necessary to restore the magnetism with a magnetizer. permanent magnet (permanent magnet), that is, permanent magnet, can be a natural product, also known as natural magnet, can also be artificially manufactured (the strongest magnet is Ndfeb magnet). A material with a wide hysteresis loop, high coercivity and high remanence, which can maintain constant magnetism once magnetized. The composition of the magnet is iron, cobalt, nickel and other atoms, the internal structure of its atoms is relatively special, and it has a magnetic moment.
