Below, you will find a selection of magnets with a central plain hole for fixing in place with a non-countersunk bolt or screw or for fixing on to a rod.

Basic ring magnets without any additional machining can be magnetized with their north and south pole on opposite circular faces or diametrically magnetized so that the north pole is on one curved side and the south pole is on opposite curved side. They are used in many everyday appliances such as vacuum cleaners plus motors, generators, rotor shafts and more. You can also use ring magnets with a piece of copper pipe to display fascinating eddy currents.
