Magnetic Product Description:
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.
Uses for our rare earth disc magnets:
With their cylinder-like proportions, these small Neodymium discs provide a concentrated holding or attraction power to a relatively small pole surface. This is beneficial to the operation of devices like switches, meters, sensors and metal detectors where reactions to a ferrous material or an electromagnetic field need to be reliable and accurate. Discs of these dimensions are also ideal for recessing into other materials like plastic or wood to create a seamless and screw-free bond between metal surfaces or to other magnets. Simple applications at home or at work include metal retrieval, tool holding and magnetic closure systems.

NB: Ranges are indicative for product category, please check individual products for specic values within that range.
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.
