These versatile high-performance ring magnets are diametrically magnetised which means their north and south poles are on opposite curved faces. They also have a small 2mm hole going through the diameter of the magnet. They are used in many everyday appliances such as vacuum cleaners plus motors, generators, rotor shafts and more.
