Magnetic Product Description:

This neodymium magnetic disc has a diameter of 15mm and a height of 3mm. It has a magnetic flux reading of 2338 Gauss and a pull force of 2.84 kilos. This product is identified by the AMF Magnetics part number 20021B.

Uses for our Rare Earth Disc Magnets:

This small Neodymium magnet is constructed from high-grade N38 magnetic material and the increased strength of the superior grade magnet means it can replace larger dimension magnets and still provide the equivalent magnetic pull-force. Rare Earth magnets have had a significant impact on modern product designs and the development of technologies that depend on small dimensions for their appeal and popularity in today’s market.

Tiny rare earth round magnets are found in miniature speakers, microphones and many other audio devices. They are also key components in electric motors, within consumer products, where they operate in conjunction with an electromagnetic field to generate sound or convert electrical current into motion. The unique combination of super strong magnetic power coupled with lightweight scale allows Neodymium magnets to enhance the performance and appearance of many modern products.

Small but powerful

I needed these for a small project and they are just perfect for that.

No FAQ available

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.
