What's the use of magnetic powder
Magnetic powder, a hard magnetic single domain particle. It can be made into magnetic recording materials such as magnetic tape, magnetic disk and magnetic card by coating it with adhesive, solvent, etc. on the surface of plastic or metal sheet base (support body). Magnetic powder is the core component of magnetic coatings and the main factor determining the magnetic properties of magnetic recording media. Magnetic powder has a great influence on the properties of magnetic recording materials.
First, NdFeB magnetic powder (hard magnetic powder); The magnetic force will remain forever after magnetization; Like a magnet; Used as: permanent magnet, such as magnet;
Second, iron cobalt nickel magnetic powder (soft magnetic powder); Magnetism is very strong when magnetizing; The magnetism disappears after leaving the magnetic field; Used in: magnetic particle clutch brake.
