A sleek and shiny nickel-coated mini magnet, this Rare Earth Neodymium disc magnet has powerful properties that mean it can stand up to some heavy lifting, despite its size. Small Rare Earth discs are super versatile because they can slip into tight places where strong holding power is required - but space is limited. Because it is the strongest type of permanent magnet, Neodymium has transformed many industries which rely on powerful and constant magnetic force and has allowed those industries to advance their technologies. They may be small, but these Rare Earth magnets have played an important role in the development of industries such as electronics, communications and design.
Look inside a phone, a sensor, alarm or an electronic item, even the jewellery you’re wearing, and you will probably find a Neodymium magnet. If you enjoy DIY and craft-making, make sure you have these small Neodymium discs in your kitbag - they have a multitude of uses, limited only by your imagination.

Surface Treatment
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.
Range and Tolerance
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.
Magnetic Properties
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.
