Do You Know These Four Main Categories of Magnets
Do you know that magnets can be divided into four main categories including NdFeB magnets, ferrite magnet, Samarium Cobalt Magnets and Alnico magnets. In the following article, I will introduce these magnets one by one.
NdFeB magnet
NdFeB magnet is a little fragile and has better machining performance. As usual, they can have centerless grinding, grinding, double-sided grinding, high-speed wire cutting, the inner circle sliced and the typical shapes include square, circle, donut, tile-shaped, trapezoidal blocks, the circular table sheet, bread-like, spherical, etc.

In ancient times, the smart Greeks and Chinese people found that there was one kinds of natural stone which had the magnetism and then they called such kind of stone as magnet.
