Neodymium Disc Magnet
This gold coated Neodymium disc magnet weighs 50 grams and has a pull force of 2.74kg. Gauss1066, GradeN42. It is 1.8mm in height and 22mm in diameter and has a direction of magnetization through height.
This Neodymium disc magnet is a beautiful little object with some incredible hidden powers. Not only is it lovely to look at, but it has a deceptive strength. Weighing just 50 grams this gold-coated Rare Earth disc magnet has a pull force of 2.74kg. Handsome, heroic and powerful, this little disc magnet stands less than 2mm high and is found in electronic devices, in the automotive industry, manufacturing, and in communications equipment.
In the home and office, it is extremely useful for securing items that you don't want to be dislodged easily - notes, memos and items that every home and office accumulate, and which need to be displayed. More than that – it can be part of the display, perfect for adding a smooth, slinky contemporary look to your décor.
There are more than just its obvious uses as a super powerful magnet. As well as the amazing Rare Earth properties of Neodymium, this gold-coated disc magnet resists corrosive forces and heat better than the standard nickel coating on most Rare Earth discs, making it more durable in outdoor applications. Gold is also highly conductive which can be helpful in electronic applications and because gold is also a generally inert material, it is less likely to irritate the skin or cause allergic reactions. People who use magnets for healing therapies choose the gold-coated magnets specifically because of those properties.
The dimensions of this strong Neodymium disc add to its holding power. It has a broad, round pole area on each side which allows it to attach firmly to ferrous surfaces and is less likely to be dislodged accidently, another reason it is ideal for artistic applications including jewellery making and in magnetic healing therapies. Because it has a slim profile and a wide flat surface, this disc magnet is also easily fitted beneath fabric or vinyl materials where it can create a magnetic seal or closure between the two surfaces. Put that all together and you have one very useful Neodymium magnet at your fingertips.
Gold-coated magnets can still rust when exposed to moisture or environmental damage. To protect your gold magnet from corrosion, consider applying a sealant to extend the life of the coating. However, keep in mind that this may slightly reduce the magnet’s overall pull strength.

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.
