Circle ring magnets are 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 magnetised with their north and south pole on opposite circular faces or diametrically magnetised so that the north pole is on one curved side and the south pole is on opposite curved side.
