Magnetic Product Description:

This neodymium magnetic block has a length of 20mm, width of 10mm and a height of 3mm. It has a pull force of 3.84 kilos. It is identified by the AMF magnet part number B-W10H3L20-N48.


Uses for our rare earth block magnets:

Slim rectangular Neodymium magnets can bond with steel or another magnet to make ideal points of attachment between the components of sophisticated electronic devices. Block magnets can be fitted into the angular perimeter of the moulded plastic bodies of a product without compromising the product’s overall weight or size. The inclusion of magnets in product designs invariably leads to a greater level of performance and a higher commercial value for that product.
Magnetic attachment using small, yet extremely strong Neodymium magnetic blocks can be discreet or even invisible, while also providing the opportunity to activate processes magnetically. Operations can be instantly activated by magnets as they fall into the field proximity of another magnet, a ferrous surface or an electrical field.
Nearly all industries at the technological cutting edge find this advantageous for the products they design, especially the Aviation and Automotive sectors. Neodymium power offers the benefits of being permanent, powerful and autonomous in terms of energy requirements. The sturdy bond that Neodymium magnets create can also be released manually by using physical force.

The magnetic bond can then be easily and endlessly reinstated using the intuitive nature of magnets to relocate themselves back to the correct position. N48 Grade magnetic power and all other grades are permanently installed during the manufacturing process and in addition to a magnet’s physical dimensions, creates options for users to attain the ideal level of magnetism suitable for their application.

Exactly what I wanted

Just what I wanted and needed. Great service. Magnets were protected with plastics between the magnets.

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.
