This Neodymium magnet is gold-coated, weighs 2 grams and has a pull force of 900g. It has a width of 3.175mm, length 3.175mm and height 3.175mm. Gauss 6447, Grade N52, direction of Magnetisation through height.
This sleek, gold-coated Neodymium block magnet is beautiful, but doesn’t mind doing the heavy lifting either. With a magnetic flux reading of 6447 Gauss and a pull force of 0.9 kilos, it’s all business, with a high magnetic strength pumping out reliable, permanent magnetic power. Neodymium block magnets are used in a staggering variety of industries and applications, in the apparatus used for metal filtration and removal and waste recycling, to sound amplification and recording. Neodymium magnets are also used in medical magnetic resonance equipment, in scientific research, electronic consumer goods and for point-of-sale advertising and display purposes.
Their power to weight ratio means these Rare Earth block magnets play a vital role in the development of smaller and lighter electronic products, such as smartphones, audio and communication equipment and alarms and sensors. Even hybrid and electric cars use Neodymium magnets. Their small size and strong magnetic field mean these block magnets contribute to weight reduction and efficiency targets while maximizing magnetic performance.
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.
