Our sturdy neodymium ring or donut magnets are best for applications that require a uniform aperture through the center of the magnet. This hole or hole allows the ring magnet to be combined on a camshaft, pin, wire or other cylindrical arm or component.

Therefore, our powerful ring magnets are commonly used in speakers, motors, pumps and sensors; in scale models, jewelry, art, crafts, woodworking and cabinet projects; used to hang artwork, signs and banners; and scientific research projects.
