This Neodymium Rare Earth disc has a diameter of 6mm and a height of 2mm. It is one of our smaller magnets, despite this it still has a strong magnetic force. It has a magnetic flux reading of 3495 Gauss and a pull force of 540 grams. This permanent magnetic disc is identified by the AMF magnet part number 20074.
This Rare Earth disc magnet may be small in size however it has a super strong pull force. This small and thin magnet is ideal for projects where minimal visual interruption is important. Often used to displaying artworks, paper-crafts, models and decorations on the fridge or other metal surfaces.
A small mark on one side of this Neodymium disc signifies the North Polarity. This makes the identification of the magnetic polarity a simple task. This is also a very handy magnet to keep in stock for identifying the magnetic aspect of other magnets. Simply hold the marked magnet close to any unmarked magnet to identify the presented magnetic face depending on whether it attracts or repels from its counterpart.

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
