Neodymium Block Magnet - 3mm x 3mm x 3mm | N50
Same Day Dispatch
Order before 1pm to qualify for same day dispatch.
This Neodymium block magnet is nickel coated, weighs 2 grams and is 3mm in width, 3mm in length and 3mm in height. It has a pull force of 0.7280kg, Gauss6142, GradeN50 and a direction of magnetisation through height.
This Nickel plated Neodymium magnetic block is a cube shape with an N50 grade, giving it a lot of magnetic power. These Rare Earth cube magnets have a sleek nickel finish and because of their shape, they have a reduced mass and are deceptively lightweight.
The cube dimensions mean they can fit into small internal spaces, so they are the right magnet for compact monitoring devices or inside sensors, in many electronic goods, microphones, speakers and other audio equipment. State of the art electronic consumer goods rely on the internal power of small Neodymium block magnets to operate reliably.
There is a surprising variety in applications for Neodymium cube magnets outside the high-tech environment. Industrial applications for these permanent magnets include low-friction, long life Brushless DC motors for cordless tools and in drone and electric vehicle technology, where power to weight ratios are key to performance and efficiency.
Permanent Neodymium magnets are the stalwarts of the magnet world, delivering constant magnetic hold without any external power requirements. The silver nickel coating over these Neodymium magnetic cubes keeps the magnet from corroding in normal atmospheric conditions.

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.
