Let me introduce one of the magnets: Neodymium Ring Magnet

Neodymium magnet, also known as NdFeB magnet, is a tetragonal crystal composed of neodymium, iron, and boron (Nd2Fe14B). In 1982, Masato Sagawa of Sumitomo Special Metals discovered neodymium magnets. The magnetic energy product (BHmax) of this kind of magnet is greater than that of the samarium cobalt magnet, which was the material with the largest magnetic energy product in the world at that time. Later, Sumitomo Special Metals successfully developed the powder metallurgy process, and General Motors successfully developed the melt-spinning process, which can prepare neodymium iron boron magnets. This kind of magnet is a permanent magnet with magnetism second only to absolute zero degree holmium magnet, and it is also the most commonly used rare earth magnet. NdFeB magnets are widely used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools.

In order to avoid corrosion damage, it is necessary to do a protective treatment on the surface of the permanent magnet material during use, such as electroplating with gold, nickel, zinc, tin, and spraying epoxy resin on the surface.

NdFeB is divided into two types: sintered NdFeB and bonded NdFeB. Bonded NdFeB has magnetism in all directions and is corrosion-resistant; while sintered NdFeB is easily corroded and the surface needs to be coated, generally galvanized, Nickel, environmental protection zinc, environmental protection nickel, nickel copper nickel, environmental protection nickel copper nickel, etc. The sintered NdFeB is generally divided into axial magnetization and radial magnetization, depending on the required working surface.
