Ring-shaped NdFeB magnets, also known as neodymium ring magnets, are a type of permanent magnet that features a hole in the center of the ring. These magnets are made from a combination of neodymium, iron, and boron, and are known for their strong magnetic properties and durability.
The ring-shaped design of these magnets makes them well-suited for use in many industrial and scientific applications, including motors, generators, loudspeakers, and magnetic bearings. They can also be used in consumer products, such as magnetic clasps for handbags and jewelry.
Ring-shaped NdFeB magnets come in various sizes and strengths, ranging from small magnets that can fit on a fingertip to larger magnets that are several inches in diameter. The strength of these magnets is measured in terms of their magnetic field strength, which is usually given in units of gauss or tesla.
