Ring Magnets
Ring Magnets are available in both strong Neodymium and cost-effective Ferrite materials. AMF’s range includes large magnetic rings up to 145mm and small options as little as 5mm, with various inner diameters and magnetisation directions (axial, radial, or diametric) to suit different applications. Most ring magnets are axially magnetised, with poles on each flat face.
Ferrite & Neodymium Ring Magnets
Ferrite ring magnets offer good corrosion resistance and perform well in humid or outdoor environments, while Neodymium ring magnets deliver superior magnetic strength in compact sizes. Coated Neodymium rings (epoxy or plastic) improve durability and reduce corrosion. Originally used in large Ferrite speaker systems, ring magnets are now essential in modern sound equipment—microphones, speakers, and pickups—where smaller, stronger Neodymium magnets enable powerful yet compact designs.
Ring magnets are highly versatile, used across industries from manufacturing and electronics to fashion and design. Their central void makes them ideal for fitting onto rods, shafts, or within assemblies, while also allowing for creative fastening options with wire, ties, or fabric stitching.
AMF Magnetics stocks an extensive range of ring magnets in various grades, sizes, and coatings. Neodymium Rings range from N35 to N52 grades, offering different magnetic strengths, while Ferrite Rings provide excellent temperature stability and corrosion resistance. Coating options include Nickel, Plastic, Epoxy, and Gold. For assistance choosing the right magnet, contact our team—plus enjoy free standard shipping Australia-wide on orders over $30.
FAQs
What is a Ring magnet?
Ring magnets operate just like a Disc-shaped magnet but have reduced magnetic holding power because of the void and the absent magnetic material. Ring magnets have a typical donut shape that helps them fit onto shafts and rods, or attach to other materials without glue or fasteners. Any type of magnetic material can be used to manufacture a magnetic ring.
How do Ring magnets work?
As with Disc-shaped magnets, the magnetic field of Ring magnets also generally flow through the height dimension. Try the FAQ & Knowledge Base pages on the AMF website for helpful technical information on how magnets work, the manufacturing processes and stories about customer applications using Ring magnets.
What are Ring magnets best used for?
Ring magnets can be used for magnetic applications of any kind but are very well suited to circumstances where the attachment of a magnet by glue or fasteners needs to be avoided. Ring magnets fit easily onto shafts and spindles to help operate equipment or monitor movement in processing equipment and alarms.
