Neodymium Ring Magnets

Neodymium ring magnets are part of neodymium magnets which are permanent magnets made from an alloy of neodymium, iron, and boron. They have the highest magnetic properties and are the most powerful commercially available magnets today. Neodymium ring magnets are disc magnets or cylinder magnets with a plain hole through the center of the magnet. They are used in many applications such as holding, motors, generators, loudspeakers, MRI machines, linear actuators, magnetic bearings, magnetic couplings.
