This neodymium magnetic disc has a diameter of 3mm and a height of 1.5mm. It has a magnetic pull force of 208 grams. It is identified by the AMF magnet part number D-D3H1.5-N50ni.
This tiny disc is certainly one of the smallest rare earth discs in our product range. Perfect for craft projects, the extremely strong hold provided by the Neodymium magnetic material goes a long way in making up for its diminutive size. Although nobody would consider this little disc heavy duty it really does hold its own when compared to the strength of other types of permanent magnets. Small rare earth magnets such as these can be found in a surprisingly large array of electronic equipment, from speakers to electric motors.
I use these in my piezo transducer/microphone housing.
They work well, but I might try the 4mm next time.
I am happy with my purchase - and will shop again with AMF Magnetics. thanks.
Amazingly strong magnets, ideal for discretely attaching my laser cut ornaments to fridges Ian’s other white goods. The photos attached shows a laser cut wooden Wombat in which I cut two 3mm holes in the head (eye) and the rear and pressed a 3mm Neodymium disc magnet in each hole. Then, hey presto, a wombat fridge magnet!
Easy transaction, fast delivery, all round great service and the magnets are as described. Very happy customer here.

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
