Magnetic Product Description:
This rare earth disc has a diameter of 15mm and a height of 3mm. It has a magnetic flux reading of 2340 Gauss and a pull force of 2.9kg. It is identified by the AMF magnet part number 20021.
Uses for our rare earth disc magnets:
People who make boxes, cases and folders for storing or transporting documents are fighting for their livelihoods in the digital age, and they are taking these gold plated 15mm x 3mm magnets with them into battle. By improving the style and ease of use of these boxes cases and folders, they rely on the adage that you only get one chance to make a first impression. As we all know, first impressions last! As many of their products are used in a work environment, they may be right.
These gold plated, yet inexpensive tiny magnets certainly attract plenty of interest. For holding, releasing and joining functions in boxes cases and folders, these little attention seekers add a timeless touch of class and elegance of use to what has previously been rather mundane, if useful items.

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.
