Despite it’s tiny proportions this disc has a strong magnetic holding force. Our Neodymium discs are made using powerful rare earth magnetic material. This rare earth disc has a diameter of 3mm and a height of 3mm. It has a magnetic flux reading of 5635 Gauss and a pull force of 0.244kg. Its part number is 20085.
Although miniature in size, these Neodymium discs have a powerful pull force and are a key component of many electronic devices. Computers, hard drives and microphones all take advantage of the reliable and stable magnetic power of these permanent magnets. Their small size makes them incredibly versatile and adaptable to fit any application.
Due to their small proportions, this small Neodymium Rare Earth magnet is also loved by craftspeople. They are often used in model making, art and creating prototypes of all sorts. These can either be used alone or in a range or magnets.

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
