Ring magnets contain a central bore hole that can be used to fix a magnet in place with a non-countersunk screw, or attached to a rod. Neodymium is the strongest permanent magnet material on the planet—approximately 10x greater than conventional magnets.

When formed into a circular ring (or donut) shape they lose some of their strength relative to a flat disc, but they gain advantages in versatility since they can be permanently attached to other objects with screws or wire, and they can placed around pipes and rods. They are also used in many appliances like vacuum cleaners, motors, generators, rotor shafts and others.
