Problems solved by technology

[0003] In the field of magnetic materials, magnetic performance indicators such as remanence, magnetic product energy, intrinsic coercive force, and coercive force of magnetic materials in the prior art cannot meet the needs of existing projects and practical applications.
At the same time, the manufactured magnetic materials will have process defects such as surface roughness, slag inclusions, and air bubbles, which will affect the application of the magnetic materials themselves.
[0004] In addition, the existing magnetic materials are relatively easy to corrode due to the rough surface or inclusion of impurities, which makes the magnetic material itself easy to wear or wear, and shortens the life of the magnetic material.
