Ring magnets are used in a variety of applications, from science experiments to medical equipment, because of the versatility of their shape and their ability to work with other components, like rods or tubes. Ring magnets have a unique polarization because the north and south poles can be segmented in a variety of ways, but always alternate around the ring. This means the poles can be in half, quarter, or even eighths.
We carry a large inventory of permanent rare earth and ceramic ring magnets in a wide range of sizes, grades and finishes which are available for immediate on-line purchase. Not all of our ring magnets are shown on this website. Contact us today if you don’t find what are looking for. In addition to the ring magnets shown here, we offer magnets with countersunk holes.

Ring Magnet Features & Characteristics
Ring magnets are flat (the diameter exceeds the thickness), circular in shape and have a hole in the center. They are not quite as strong as some of their disc counterparts due to having less magnetic volume, but the hollow center makes them quite versatile, as they can easily slide onto rods and tubes.
Available Grades for Ring Magnets
Neodymium ring magnets come in grades ranging from N30 to N35. Grade 5 ceramic ring magnets are available as well.
Both large and small ring magnets are ideal for many manufacturing applications, audio equipment, high-performance motors, work holding assemblies, industrial lifting applications, science projects and much more.
