Neodymium Ring Magnets
Neodymium magnets are more powerful than any other magnet and ring shaped Neodymium magnets are one the most versatile and popular shapes in the large Frenergy range. Ring magnets of most sizes can be used in a wide range of applications that vary from simple craft and hobby type uses to their inclusion inside highly technical commercial products. In some applications, the opposing North and South poles are used to bind to surfaces together and in others, the magnet is used to bond to a ferromagnetic material or metal surface. Ring magnets have long been associated with audio loudspeakers and microphones where the ring shape helps translate sound wave vibrations into electrical signals for amplification and clarity. Small, yet extremely strong rare earth ring magnets have led to innovations in this type of equipment that allow it to have more compact dimensions while simultaneously increasing the performance of these audio products and devices.

Surface Treatment
The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.
Range and Tolerance
Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.
Magnetic Properties
Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
