Neodymium Block Magnet - 8mm x 4mm x 3mm | N50

Magnetic Product Description:

This neodymium magnetic block has a length of 8mm, width of 4mm and a height of 3mm. It has a magnetic flux reading of 6845 Gauss and a pull force of 1.3 kilos. It is identified by the AMF magnet part number B-W4H3L8-N50.



Uses for our rare earth block magnets:

For the needs of commercial products and also home-based artwork, small yet powerful Neodymium Block magnets are often used to save space while still meeting magnetic pull-force requirements. The N50 Grade of this magnetic product increases the magnetic field strength without needing to employ a thicker, heavier or larger magnet. Reductions in weight are becoming increasingly important to improving the performance and value of electronic devices and equipment and in a range of other high-end products and Neodymium magnets have been crucial to achieving this aim. Luxury and high-tech products often include magnetic hold as a point of difference with a competitor's product or design. Magnetic closures inside the covers of binders, scrapbooks, brochures or invitations can appear to be innovative, unique and more contemporary. Similarly, magnetic hold can also be applied to jewellery and fashion accessories. Particular applications may find the straight edge and right-angled corners of Rectangular magnets an advantage. Other applications may find Disc or Ring-shaped magnets more suitable.

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.

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.

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.
