This neodymium magnetic block has a length of 20mm, width of 8mm and a height of 2mm. It has a pull force of 1.86 kilos. It is identified by the AMF magnet part number B-W8H2L20-N42.
Neodymium Block magnets come in a range of different dimensions and are also sometimes referred to as rectangular magnets, square magnets, bar magnets or cube magnets. Rare Earth or Neodymium magnets are the most powerful of permanent magnets and since the discovery of this rare earth mineral in the 1980s it has superseded traditional types of magnets in most commercial operations. This equal sided Neodymium block magnet fits into the cube magnet category. Often described as silver magnets for their chrome-like appearance, Neodymium magnets are usually Nickel plated. The coating helps to provide some resistance to corrosion however there are other coatings such as Gold, Teflon and Parylene-C that are more suitable for particularly humid environments. Another helpful aspect of the Nickel plating is that Neodymium magnets are easily identifiable as the silver surface is distinctive from other types of magnetic material which are generally darker in colour.

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.

The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
Magnet Safety Warning
Magnets can pose a serious swallowing hazard to children. If multiple magnets are swallowed or inhaled, they may attract to each other inside the body, causing severe internal injuries, infection or death.
In accordance with Australian Government and ACCC safety guidelines, children's toys containing magnets must display appropriate warning labels.
Please note: we do not manufacture or sell magnetic toys.
AMF Magnetics accepts no liability for injury, damage or loss caused by the misuse, improper handling or unintended use of magnetic products. Read More
