Magnetic Product Description:
This rare earth ring magnet has an outside diameter of 12.7mm, a countersunk hole with an inside diameter of 3.12mm and a thickness of 4mm. It is identified by the AMF magnet part number 23011.
Uses for our rare earth ring magnets:
These Neodymium Rings are N42 Grade for extra holding ability and have a countersunk hole for convenient attachment with a flat-head screw. Standard Ring magnets are practical and the addition of the countersunk void area in this item makes it even more practical. Using the hole for attachment with a screw leaves the North magnetic pole exposed and able to attract or attach to metal surfaces. This can be a convenient method of fitting protective screens or weather shields into place or for closure systems on cupboards and drawers. Attaching countersunk magnets to any type of surface with a screw makes it able to hold metal items. This can include signage, artwork, advertising material, partitions and privacy screens or everyday items like regularly used tools and equipment. Magnetic attachment can be applied in a temporary or permanent fashion, giving more flexibility to the way items are secured or stored. They have a variety of helpful applications on Trucks, Cars and Vans. Use them at home or in the workplace or even on a camping vacation!

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.
