Everyone knows what “magnet” is, but he/she must do not know what the magnet is made by. Actually, Magnet is made by lodestone. When the magnetic qualities of lodestone are passed into the magnetic substance, it will be the permanent and long-lasting magnet. We can also define that the magnet is the material or the object that can produce the magnetic field which is invisible but is the most remarkable property of the magnet. In addition, the most common type of rare-earth magnets is “Neodymium-iron-boron” magnet.
Neodymium-iron-boron magnet is generally known as “NdFeb magnet”, “NIB magnet”, “Neo magnet”. It is mainly made of many substances, including alloy of neodymium, iron, and boron. This kind of magnet can not only replace other types of magnet in many applications, but also provide the highest available.
The greater strength NdFeb magnet can supply with the given application in the modern products, such as hard disk drive, motors in cordless tools, etc. Therefore, NdFeb magnet is the very significant material in the industry and technology.
