Neodymium Block Magnet - 5mm x 3mm x 2mm | N50 | Black Nickel Coating
Same Day Dispatch
Order before 1pm to qualify for same day dispatch.
Neodymium magnet, black nickel-coated, with a pull force of 0.6300kg. This block magnet weighs 10 grams, is 5mm in length, 2mm wide and 2 mm in height. Gauss6791, GradeN5 and direction of magnetisation through height.
This shiny, black nickel-coated block magnet is not just about the looks. With a magnetic flux reading of 6791Gauss and a strong magnetic pull force of 0.630 kilos, this magnet is one of our big hitters. These rare earth magnets, also known as neo blocks, are one of the key components in metal detection and in metal retrieval. Neodymium magnets are also hard at work in microphones and alarms, speakers and other audio equipment. In fact, it’s in the innovative communications field where these magnets really get to strut their stuff. The shape of this Neodymium rare earth magnet means it is a useful component in magnetic door-latch products and magnetic tool holders. They’re called channel magnets because they can fit into the length of a steel channel and be held there with adhesive. Very handy, very versatile.

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.
