Direction of magnetic for Ring Magnets
For the appearance, NdFeB ring magnets are just disc neodymium magnets with a hole in it. The hole can be made on any position of the disc magnets, but it almost made in the center of disc magnets.
Most of the ring neodymium magnets are just magnetized through height or thickness. If you want the neodymium ring magnets magnetized through diameter, please let me know when inquiry.
Applications of NdFeB Ring Magnets
With good magnetic performance, NdFeB ring magnets are used more and more in different fields. Magnet rings divided into neodymium magnet rings, ceramic magnet rings and smco magnet rings. Neodymium rings are needed when strongest magnetic performance required in limited size. For small neodymium rings which axially magnetized, which is often used on precise electronics.
Teflon coated neodymium ring magnets are made for applications that require low friction and high resistance to liquids and ultrasonic cleaning. Teflon coating also helps protect the magnet from chipping or breaking. High-performance Teflon(PTFE)-coated neodymium ring magnets are water resistant and machine washable, ideal for clothing garments and accessories.
