HuanTongcx is a professional magnetic materials manufacturer over 18 years.

Permanent Magnet

Permanent magnet is materials that can continuously generate a magnetic field, usually made of iron, cobalt, nickel and their alloys. Unlike temporary magnets, permanent magnets can still maintain their magnetism without an external power source or magnetic field, and can maintain their performance for a long time. Different types of permanent magnet materials have different magnetic strengths, and some can maintain their performance even at high temperatures. Permanent magnets are widely used in motors, generators, speakers, sensors and various electronic devices, and are an indispensable material in modern technology. If you are looking for a permanent magnet manufacturer, welcome to contact HuanTongcx!
