Same Day Dispatch
Order before 1pm to qualify for same day dispatch.
This rare earth disc has a pull force of 58 grams, a diameter of 2 mm and a height of 1 mm. It has a magnetic flux reading of 4840 Gauss.
These 2mm x 1mm rare earth disc magnets are small, but extremely strong and highly versatile. They are are irreplaceable in high-tech sound recording, communications equipment and a range of other electronic devices.
The small dimensions and the ability of these discs to hold and bond with ferrous material makes them popular with producers of custom-made fashion items and with innovative hobbyists. Neodymium disc magnets are used in the creation of intricate designs that keep parts or components secure while maintaining easy access for servicing.
They can be fitted into plastic moulds, glued into drilled out recesses or even sewn into garments to create a bond with metal or an opposing pole magnet. They can also be used in multiples, so you can add or subtract magnetic material to adjust these strong magnets to your needs.
Neodymium disc magnets are made from N45 grade Neodymium material which means that while miniature in size, they’re the gladiators of the magnet world, providing superior heavy duty hold compared to more traditional ferrite or ceramic materials.
If you are after a professional finish to small craft projects, Neodymium disc magnets are a fantastic choice as they’re easily hidden from view. Rare earth disc magnets are found in a huge array of electrical devices and equipment and they are key components in many modern products. The neodymium magnetic material is nickel-coated so they resist corrosion and where aesthetics matter, the silver or chrome finish will add lustre and quality to your project.

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.
