Magnetic Product Description:
This strong neodymium cylinder has a diameter of 20mm and a height of 25mm. It is an N42 grade rare earth magnet. It is identified by the AMF magnet part number 21012.
Uses for our neodymium cylinder magnets:
Cylinder Magnets like this N42 Grade item allow Engineers to design effective and accurate monitoring equipment such as sensors. gauges and actuators for industrial processes in factories and material processing plants. Cylinders emit magnetic fields that are both deep and superior in strength to same diameter disc magnets. Their field is also more condensed due to the elongated shape and relatively small poles, and this provides added accuracy as they react to metallic materials or electromagnetic fields in their vicinity or field range. They have permanent power and no moving parts which ranks them as ideal candidates for use in reliable, long-term measuring devices with minimal service requirements that continue to operate unaffected by grime or dusty environments. When a measuring device needs to address elements of safety, security and accuracy, Neodymium cylinder magnets are ideal.

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.
