Sell neodymium sphere magnet nickel coating

Neodymium magnet is the strongest magnet in the world till now that can lift up to ***0 times its own weight, it is mainly made of Neodymium, Iron and Boron. It is high remanence, high coercive force, high energy product and high performance/cost ratio. Neodymium magnet is anisotropic and only magnetized in one direction.
