Round Neodymium Magnet is the shape of a neodymium magnet. Neodymium magnet is also called neodymium iron boron magnet. Its chemical formula is NdFeB. It is an artificial permanent magnet and has the strongest magnetic force so far. Neodymium magnet was invented in 1982 by Mr. Sagawa and others of Sumitomo Special Metals. From its chemical formula, it can be known that it is mainly composed of chemical elements such as neodymium, iron, and boron. Neodymium magnets with strong magnetic properties are widely used in electronic products, such as hard drives, mobile phones, headphones, and so on.

　　NdFeB magnets are the magnets with the highest commercial performance found so far. They are called magnet kings. They have extremely high magnetic properties and their maximum magnetic energy product (BHmax) is more than 10 times higher than that of ferrite. Its own machinability is also quite good. Operating temperature up to 200 degrees Celsius. Moreover, its texture is hard, its performance is stable, and it has a good price/performance ratio, so it is widely used. But because

　　Its chemical activity is very strong, so its surface layer must be treated. (such as Zn, Ni, electrophoresis, passivation, etc.).

　　With nickel, zinc, or copper coating, neodymium magnets have excellent resistance to atmospheric media, and neodymium magnets are currently the strongest magnets on the market, known as the king of magnets. They are highly magnetic, and their maximum energy product (BH) max is 10 times greater than that of ferrite magnets. NdFeB has excellent machinability and operating temperature up to 200°C. Also, neodymium magnets are widely used in various industries because of their stable performance and good cost performance.
