This rare earth pot magnet has a diameter of 20mm, a countersunk hole diameter of 4.5mm and a thickness of 7mm. It has a pull force of 6kg and a weight of 13 grams. It is identified by the AMF magnet part number AMFYPA20.
Thanks to the concentrated strength of our 25mm Neodymium Pot Magnets they can be used for a multitude of holding applications. They offer versatility and excellent value for money, so these Neodymium Pot Magnets can be applied to various home, office and industrial duties. They have a high strength magnet in a mild steel casing that protects it from collision damage and also deflects its magnetic power to the base, magnifying its strength and holding power. Countersinking the attachment screw means the base surface remains flat for maximum surface area exposure. This ensures a secure and sturdy hold in both vertical and horizontal positions.

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
