This rare earth ring magnet has an outside diameter of 22mm, an inside diameter of 4.5mm and a thickness of 10mm. It is identified by the AMF magnet part number 23004A.
The ring shape of these Neodymium magnets makes them ideal for applications that require the magnet to be fixed onto a soft material or in a semi-permanent location. The centre hole allows them to be easily secured using wire, rope, string or cable ties. Likewise ring magnets are easily stitched into flexible materials such as fly screen, shade cloth or textiles. Ring magnets are a popular choice for people constructing semi-permanent structures such as campsites, sporting events or festivals as they can be easily set up and removed whilst providing reliable holding power whilst in use.

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.
The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
