This Rare Earth disc magnet is north-marked, and has a diameter of 10mm and a height of 2mm. It has a pull force of 1.48 kg. This product is identified by the AMF Magnets part number 20053A.
This Magnet has been magnetised to N52 Grade which is our strongest grade. Though small, this magnet has incredible holding strength that is mostly required for specialised manufacturing designs or fabrications such as those in the Military, Aerospace, Science or Defence departments. Small magnets like these can be used in combination with equal or weaker grade magnets to create the correct pull and release pressure threshold. They are popular size with designers, engineers and applications where maximum pull force is required.
I’ve purchased these small disc magnets a couple of times now to make art magnets and they are the best quality with great pull strength, so I can make products that look professional and function well too, where cheaper magnets are not strong enough.
Magnets arrived super quickly, and they're exactly as described. Good job.

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.
The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
