The size of a ring is given by specifying the Outer Diameter x Inner Diameter x Thickness. Like discs, most rings are magnetized through their thickness so that the north pole is on one flat surface and the south pole is on the opposite flat surface. Ring magnets are a good choice when you want to bolt or screw the magnet in place.
