This rare earth disc has a diameter of 12.5mm and a height of 4mm. Powerful Rare Earth magnetic material allows for an extremely strong magnetic force relative to size. This strong magnetic disc has a magnetic flux reading of 3396 Gauss and a pull force of 3.1kg. It is identified by the AMF magnet part number 20023.
Neodymium Disc Magnets are Ideal for joining, holding and connecting different materials such as paper, glass, fabric, timber, plastic or metal. This disc magnet is able to join, hold and release without damage to the material involved. Repositioning items can be done with little or no penalty, unlike with screws, nails and hooks.
Art galleries, museums and exhibitions keep these Neodymium Disc Magnets close at hand. They are strong and durable enough to hold important items in place, yet small enough not be seen. Create magnetic display cases, mount artwork or artifacts with these Discs. See how the Museum of Australian Democracy uses out Magnetic Discs Here.
Used for my son’s D&T HSC project. Arrived quickly . No dramas. Perfect. Thanks
Used the magnets on home made knife sharpener.
Good product range.
Didn’t have to wait too long for delivery.
Will probably use again.

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
