Large, 40mm diameter neodymium, samarium cobalt, and ceramic ring magnets used in industrial applications.
These large ring magnets all measure 40mm (1.57") either in their outer diameter or inner diameter and are made from a range of magnetic materials. Below you will see ring magnets made from super-strength neodymium, high maximum temperature samarium cobalt and great value ceramic. Ring magnets are often used in motors, generators, audio equipment, conveyor systems and magnetic separation applications.
