Permanent magnet materials are mostly made by NdFeb, ferrite, aluminum nickel cobalt, cobalt and so on, and have the characteristics of large correcting force, stable performance and so on. These materials have magnetism after magnetization by magnetizing machine.
Neodymium magnet is an intermetallic compound composed of neodymium, iron and boron. After magnetization, its magnetic performance is not only strong, and can be maintained for a long time, enduring, is an excellent permanent magnet material.
Here are the different shape of neodymium magnetization directions:
