This large diameter Neodymium Ring Magnet is axially magnetised through the relatively thin height dimension. The thinner profile reduces its magnetic power considerably so it is incorporated into specialised industrial and scientific equipment that requires precise and consistent interactions in their operation. This can involve valves and switches for monitoring and measuring equipment for industrial processes and devices for the associated warning systems. Neodymium Ring magnets are extremely versatile and can be applied in domestic environments or in-home hobbyist or workshop situations where they can be used to hold metal tools or fabrications in place. Ring-shaped magnets are easily attached permanently or temporarily with wire, cable-ties, string or even thread, to just about any surface.

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.
