A neodymium segment magnet is a type of magnet that is made from neodymium, iron, and boron. It is a powerful and strong magnet that is commonly used in various applications such as motors, generators, magnetic separators, and magnetic therapy devices.The neodymium segment magnet is shaped like a segment or arc, with a flat surface on one side and a curved surface on the other. This design allows for a larger magnetic field to be generated, making it more efficient and effective in its applications.Neodymium segment magnets are also known for their excellent resistance to demagnetization, which means that they can retain their magnetic properties for a long time without losing their strength.
