This neodymium disc has a pull force of 63 grams, a diameter of 2mm and a height of 1mm. It has a magnetic flux reading of 5022 Gauss.
It may not look impressive, but this tiny Neodymium rare earth magnet has helped out in the aerospace industry, in communications and electronics development, and the growing electric and hybrid auto industry. Not bad for a magnet that is just 2mm x 1 mm in size. And while size might matter in some areas, when it comes to magnets it’s all about intensity.
Neodymium discs have an excellent strength-size ratio. The N48 Grade magnetic material used in this magnet is the second highest available and increases its field intensity comparable to that of a much larger magnet.
That means where space and weight are critical, these small Neodymium disc-shaped magnets are perfect where space is restricted or a precise level of magnetic force is required for the operation of a device or piece of technical equipment. The low height dimension associated with disc-shaped magnets enables product designs with slimmer and sleeker features, and large-scale manufacturers of all manner of products include these small, powerful magnets in the design of their products.
The influential or attractive fields of permanent magnets play an important role in a vast range of modern technologies. In aerospace projects, where fuel loads and energy is largely finite, the permanence of magnetic power is critical. This tiny 2mm x 1mm Neodymium disc magnet can pack a punch, and deliver force equal to that of much larger magnets - it’s small but mighty!

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.
