Iron boron, also known as NdFeB magnet, is a tetragonal crystal formed by neodymium, iron and boron (Nd2Fe14B). Neodymium magnets were discovered by Masato Sagawa of Sumitomo Metal in Japan in 1982. The magnetic energy product (BHmax) of this magnet is greater than that of samarium cobalt magnets, and it was the material with the highest magnetic energy product in the world at that time.
Strong NdFeB magnets are like electricity, invisible and intangible. Only when iron is close can you feel the magnetic force. Magnets are easy to make and are quite common. Everyone knows that there is a gravitational field between substances. Similar to the magnetic field, it is a field that fills the space around the magnet. The size of the magnetic field can be expressed by the number of imaginary magnetic lines of force. The denser the magnetic lines of force, the stronger the magnetic field. On the contrary, the sparser the magnetic lines of force, the weaker the magnetic field.

In the past two years, the price of high-temperature resistant samarium cobalt magnets has been rising and rising again. Why do the prices of high-temperature resistant samarium cobalt magnets and many other magnets continue to rise instead of falling? In fact, this is mainly because our high-temperature resistant samarium cobalt magnets and other magnets require various rare earth elements in rare earths. These elements are indispensable in our conventional magnet production process, so the price of high-temperature resistant samarium cobalt magnets rises with the price of rare earths. The main reasons for the rise in rare earth prices are the following two points:
