Magnetic Product Description:

This neodymium magnetic block has a length of 20mm, width of 5mm and a height of 5mm. It has a pull force of 3.5 kilos. It is identified by the AMF magnet part number B-W5H5L20-N42.

Uses for our rare earth block magnets:

Small Neodymium block magnets are far stronger than traditional ceramic style magnets of similar dimensions. Uses for these rectangular magnets throughout industry, and society, in general, are vast, and new applications are constantly being discovered by engineers and scientific researchers.
Simple, time-saving and convenient uses can also be found at home or in the office. Anywhere a bond with steel or suspension of metallic items is required, small, strong Neodymium bar magnets can be a convenient solution. Hanging signage and advertising material magnetically is commonplace in the retail sector.
Hobbyists find small magnets can make their creations collapsible for transportation to exhibitions or gatherings, where they can then be quickly reassembled for display. Magnetic bond is appealing for its fast, simple operation and the non-invasive nature in which it bonds with metal surfaces or other magnets with the opposite pole.

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.
