Neodymium magnets, also known as rare earth magnets, are permanent magnets made from an alloy of neodymium, iron, and boron. Known for their strong magnetism, they are commonly used in a variety of applications including motors, generators, speakers, and sensors.

　　A ring neodymium magnet is a permanent magnet made of an alloy of neodymium, iron, and boron. It is shaped into a ring or circle and is known for its strong magnetism. These magnets are commonly used in motors, generators, and other applications that require a circular magnetic field. They are also used in sensors and speakers, as well as a variety of other industrial and consumer applications. Neodymium magnets are often preferred over other types of magnets because they are smaller and stronger, making them more versatile and efficient in a variety of applications.
