Neodymium Ring magnets are used in many modern-day products and appliances. Permanent magnets and their magnetic fields can be used to operate electronic devices and sound and communications equipment. Other uses include computers, smartphones, televisions, speakers and electric motors.
Ring-shaped magnets are sometimes applied to pipes that contain fluid to descale or modify the passing contents. In less commercial environments, Neodymium ring magnets make handy hanging or attachment mechanisms for garments and coverings.
The hole in the strong magnet ring makes it easy to secure in place with wire, string or sewing thread. Ring magnets are sometimes paired with a steel washer to form a closure system on each side of an opening. Small Neodymium ring magnets are also popular with scale model makers and those who want to add a magnetic aspect to their crafts and hobbies.

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.
