Magnetic Product Description:
This rare earth disc magnet has a diameter of 4mm and a height of 2mm. It has a magnetic flux reading of 4667 Gauss and a pull force of 340g. Its part number is 20082.
Uses for our rare earth disc magnets:
Small but powerful, these N42 Grade Neodymium Discs will hold many times their own weight. They can hold metal tools and instruments conveniently in place or be used by model makers and fabricators to keep components in the correct position without the use of glues or screws. Magnetic fields are used in many Electrical devices and Scientific research projects where their permanent, predictable and consistent power helps in the development of new technologies and more efficient 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.
