Magnetic Product Description:
This small rare earth ring magnet has an outside diameter of 5mm, an inside diameter of 2.5mm and a thickness of 4mm. It has a pull force of 710 grams. It is identified by the AMF magnet part number 23023A.
Uses for our rare earth ring magnets:
This is a specialised Ring Magnet that is magnetised in the factory with the poles on the curved diameter surface. This Diametric Orientation is a unique customer requirement for their product or manufacturing process. As well as being higher N42 SH Grade Neodymium material, it is also resistant to temperatures up to 180° Celcius which allows it to maintain its magnetic power under high-temperature production environments. Diametric magnetisation is not suitable for most general purpose applications.

NB: Ranges are indicative for product category, please check individual products for specic values within that range.
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.
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.
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.
