Neodymium ring magnets, FEN35, N38, N40, N42, N45, N50, and N52, come in various sizes. When we refer to them as ring magnets, tubular magnets, or perhaps permanent magnets or rare-earth high-strength neodymium ring magnets, they are very similar, differing only in height or length.
Neodymium ring magnets are commonly used in loudspeakers, jewelry, and home offices.
The magnetization direction is always axial, but some.
customers use them to assemble sensors, where the magnetization direction is azimuthal.
NdFeB permanent magnets possess excellent magnetic properties and are widely used in electronics, electrical machinery, medical devices, toys, packaging, hardware machinery, aerospace, and other fields. Common applications include permanent magnet motors, loudspeakers, magnetic separators, computer disk drives, and magnetic resonance imaging equipment.
