Neodymium Block Magnet - 10mm x 2.8mm x 1.9mm | N50 | Black Nickel Coating

Magnetic Product Description:

This neodymium magnetic block has a length of 10mm, width of 2.8mm and a height of 1.9mm. It has a magnetic flux reading of 4537 Gauss and a pull force of 0.827 kilos. It is identified by the AMF magnet part number B-W2.8H1.9L10-N50Bni.


Uses for our rare earth block magnets:

Rare Earth Block magnets are available in every size from large to small. They are used in a wide range of applications and have acquired various descriptive names including rectangular magnets, square magnets, bar magnets and cube magnets.

Neodymium was first discovered in the 1980s and it has largely superseded traditional types of magnets in most commercial operations where the strength of Neodymium type of magnet relative to its size is valued. However, older types of permanent magnets still have their place, particularly in high temperature and moisture-laden environments that would otherwise be detrimental to Neodymium magnets.

In order for Neodymium magnets to be used in high humidity environments a special coating such as Teflon, Gold or Parylene-C is often required. However, most Neodymium blocks come with a standard Nickel coating that provides a reasonable level of resistance to corrosion.

NB: Ranges are indicative for product category, please check individual products for specic values within that range.

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.

neo magnet revives old model train

I have a 1949 era Hornby Dublo loco that would not run because the magnetism had gone from the horseshoe style magnet. The old magnet would not respond to being remagnetized. After checking polarity of the old magnet and the neo I placed a 10mm x 2.8mm x1.9mm magnet on the tips of the horseshoe magnet. The loco now runs as it should and draws less current that original.
