This Rare Earth Neodymium disc magnet is 3mm x .5 mm N45, with a pull force of .184 kg, axially magnetised, is 1.5mm in height with a diameter of 3mm.
This Neodymium magnet is small but powerful, perfect for projects which require a strong hold without being obtrusive. Because it has a sleek gold coating, it it has an attractive lustre, and is the magnet of choice for artists, fashion and jewellery designers, craftspeople and in electronic applications. The simplicity and speed in which a magnetic bond can be applied or removed is ideal for use in these types of creative activities. Jewellery makers can adapt a Neodymium small disc magnet for clasps and attachment methods to give their creations a more contemporary feel or to intentionally move away from the traditional use of clasps and pins. These magnets are useful in so many ways - even in stationary products such as wedding invitations and gift packaging, where these attractive and powerful magnets can be incorporated into the design for closure on envelopes and gift packaging. Any project requiring an aesthetic appeal while still being functional is ideally suited to these small Neodymium gold coated disc magnets.
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.
