Neodymium Ring Magnets

Ring Magnet Info

Our ring magnets are neodymium magnets (NdFeB) and are the strongest rare earth permanent magnets available. We offer a vast selection of strong neodymium ring magnets in sizes from tiny to large and can be used for many different applications. Ring magnets are often also referred to as donut shaped magnets, or magnets with a hole. Sizes range from 1/16" or about 1.5mm, all the way up to 3" or about 75mm. We also have popular sizes like 1/4", 1/2", 3/4", 1", 2" with many sizes for ID and countersunk holes. You can use our magnet finder tool and select metric sizes to find close equivalents to popular metric sizes like 5mm, 10mm, 25mm, 50mm diameters, hole size or thicknesses, etc.

What is a ring magnet? - A ring magnet is essentially a round disc magnet or cylinder magnet with a hole in the center. Ring magnets are also sometimes called donut magnets, hollow cylinder magnets or tube magnets.

What are ring magnets used for? - Ring magnets are used for many applications such as speakers, motors, sensors, craft, hobby and DIY, as countersunk magnets and magnetic clasps and more!
