This Rare Earth ring magnet has an outside diameter of 12.5mm, an inside diameter of 3mm (to 9mm) with a countersunk hole through the south face, and a thickness of 6mm. It has a pull force of 3.9 kg. It is identified by the AMF magnet part number 23012 Sth.
This Neodymium ring magnet has a countersunk South face for easy attachment using a flat top screw. This practical and convenient magnet is also available with the corresponding North countersunk face to form a matching pair. When used together the outward faces attract and bond to each other. This is a simple yet highly effective means of bonding any non-metallic material to one another. Simply screw the magnets into plastic, timber, ceramic or any other non-ferrous substrate. They are commonly used as a pair for cabinetry closing systems and have the ability to solve a huge number of difficult bonding problems by using magnetism when no ferrous metal is present. These magnets can also be used as a single magnet to attach to any ferrous surface.

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
