Rare Earth Magnetic Disc Product Description:
This Neodymium Rare Earth disc has a diameter of 5mm and a height of 4mm. It has a magnetic flux reading of 5596 Gauss and a pull force of 800g. This permanent magnet has a nickel coating for corrosion resistance and for the prevention of chips. It is identified by the AMF Magnets part number 20079.5.
Uses for our Rare Earth Neodymium Disc Magnets:
Although small, this strong magnet is suitable in many industries and applications. Frequently used in artistic endeavours, as well as in industrial and engineering applications. You can spot these strong magnets in electric and communications equipment, as clasps in product packaging or fashion garments and more. The perfect all rounder for all your magnetic needs.
The profile of this magnet gives it superior holding capacity over thinner magnets of the same diameter and magnetic grade. This thicker profile enables easy manipulation as it can be pushed or slid by applying sideward force. This attribute makes it ideal for applications that require objects to be removed or repositioned on a frequent basis.

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.
