Neodymium Block Magnet - 100mm x 25mm x 25mm
Magnetic Product Description:
Part number 22000C - This strong magnet has a length of 100mm, a width of 25mm and a height of 25mm. We recommend extreme care be used at all times with this magnet as serious injury will occurr if mishandled. Like the bulk of our Neodymium magnets, this block has a nickel-copper coating.
Uses for our strong rare earth block magnets:
Powerful Neodymium magnets can cause serious personal injury and should be handled with extreme caution. Magnets this size are extremely powerful and are used in the operation of metal separation equipment and other industrial uses. They are sometimes used to collect metallic objects and swarf in commercial premises or in other cases are used for the purpose of conditioning water. Large Neodymium magnets are used to build electric generators and are also used as magnetic stirrers, metal detectors, tool and knife holders, wall stud finders and for retrieving all manner of metallic objects.

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.
