Neodymium Cylinder Magnet - 12mm x 50mm | N48
Magnetic Product Description:
This popular rare earth cylinder has a diameter of 12mm and a height of 50mm. It is an N48 grade rare earth magnet. It has a magnetic flux reading of 7048 Gauss and a pull force of 7.87kg. It is identified by the AMF magnet part number C-D12H50-N48.
Uses for our rare earth cylinder magnets:
Thin, Neodymium cylinder magnets are, among other factors, favoured for their ease of relocation and handling due to their elongated shape. The shape and direction of magnetisation allow the magnet protrude high above the metal surface it attaches to and able to be grasped and then removed or replaced with ease. Axially magnetised cylinder magnets like this one have North and South poles on the tiny round, flat surfaces at each end with the permanent magnetic field passing between them. The strong magnetic field of a Neodymium cylinder magnet is more concentrated than that of discs or block magnets due to the exaggerated length which is able to offer unique advantages in certain applications. Magnetic locks, sensors and alarms react more accurately and more reliably with this type of concentrated magnetic field. Contact-free magnetic couplings that can penetrate impervious barriers to transfer power also require the deep fields emitted by cylinder magnets to operate successfully.

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.
