As one of the most important application fields of rare earth materials, NdFeB materials are one of the important basic materials supporting the modern electronic information industry and are closely related to people's lives. With the popularization of communication equipment such as computers, mobile phones, and car phones, and the rapid development of energy-saving automobiles, the world's demand for high-performance rare earth permanent magnet materials has grown rapidly. Neodymium Iron Boron Magnets are currently the most commercially available magnets, and they are called the Magnet King.

Regarding the manufacturing of neodymium magnets, as many reports have said, it is impossible to talk about it without China. This is because most of the Dy mixed in magnets is mined in China, but China has begun to restrict exports.

Neodymium Magnets are currently the most commercially available magnets. It can be said to be the "magnet king" in the magnet world. It has extremely high magnetic properties and its maximum energy product is more than 10 times higher than that of permanent magnet ferrites.

The machining performance of neodymium magnet itself is also quite good: the working temperature can reach 200 degrees Celsius. Moreover, its hard texture, stable performance, and good cost performance, so its application is extremely wide. But because of its strong chemical activity, it must be coated on the surface.

This magnet material was introduced by Sumitomo Special Metals in 1984 and is the strongest magnet on the market. The strongest magnet before this was the Smco Magnet developed in Europe and America. Both of these magnets are now used as parts of small motors or speakers. Many machines can be miniaturized because of their small and powerful magnets.

After using this kind of magnet, when it comes to magnets, people will not say "magnet is a substance that adsorbs iron, cobalt, and nickel". Rather, it will think of "any substance has magnetic induction", but iron, cobalt, and nickel are more magnetic, and the magnetic induction phenomenon is more obvious. If other substances do not use strong magnets, no magnetic induction phenomenon can be seen. In fact, magnets are divided into two types: paramagnetism that attracts iron and diamagnetic repulsion.
