Magnetic Product Description:
This rare earth disc has a diameter of 2.5mm and a height of 2mm. It has a magnetic flux reading of 5597 Gauss and a pull force of 158 grams. It is identified by the AMF magnet part number 20100.
Uses for our Rare Earth disc magnets:
This Rare Earth N42 grade magnet is stronger than N38 grade magnets of the same dimensions.It is used commonly where a specific pull- force is essential to the operation of a device or apparatus, such as electronic equipment, computers, smartphones and sensitive monitoring systems.The increased pull force of Grade N42 helps maintain magnetic energy and performance in small or restricted space applications.
Industrial designers, Engineering shops, Fabricators and Manufacturers of Electronic equipment all find uses for these magnets in their products.

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.
