Chinese Supplier Bar Quality Permanent Neodymium N52 High Strength Magnet
NdFeB magnet is tetragonal crystal of Nd, Fe and B (Nd2Fe14B). In 1982, Mr. satakawa discovered neodymium magnet(NdFeB magnet). The BHmax of this magnet was larger than SmCo magnet’s, and it was the largest material in the world at that time. Now, this magnet is a permanent magnet that its magnetism is second only to absolute zero degree holmium magnet, and it is also the most commonly used rare earth magnet. NdFeB magnets are widely used in electronic products, such as hard disks, mobile phones, earphones and battery powered tools. In order to avoid corrosion damage, it is necessary to protect the surface of permanent magnetic materials by using electroplating with gold, nickel, zinc and tin, and spraying epoxy resin on the surface.
Neodymium magnets have been widely used in many fields, especially in modern high-tech fields. Its application can be divided into the following categories: 1. Electric mechanical energy conversion, such as motor, loudspeaker, VCM voice coil motor, etc; 2. Mechanical energy - electric energy conversion, such as: generator, receiver, measuring instrument, etc; 3. Mechanical energy -- mechanical energy, such as magnetic separation, magnetic suspension, magnetic transmission, magnetic suspension, magnetic sucker, etc; 4. Using the physical effects of magnetic field, such as magnetic resonance, magnetization dewaxing, magnetization oil saving, etc.
