Neodymium Cylinder Magnet - 12.7mm x 25.4mm | N45
Magnetic Product Description:
This popular rare earth cylinder has a diameter of 12.7mm and a height of 25.4mm. It is an N45 grade rare earth magnet. It has a magnetic flux reading of 6444 Gauss and a pull force of 8.02 kg. It is identified by the AMF magnet part number C-D12.7H25.4-N45.
Uses for our rare earth cylinder magnets:
Cylindrical magnets constructed from powerful Neodymium material are highly suited to applications that require more magnetic hold than a disc-shaped magnet are able to provide. Cylinder shaped magnets have elongated height dimensions. The space between the North and South poles of a cylinder is larger than that of other shapes. As a result, cylinder magnets contain more Neodymium material and are therefore magnetically stronger for their size. The exaggerated height dimension of a cylinder magnet also has an influence on how its magnetic field behaves,i.e. It increases the field intensity while at the same time making the field more concentrated. These unique characteristics are important for sophisticated scientific applications as well as simple bonding and metal detection purposes. When a strong, permanent, round, rare earth magnet is required for your application, Neodymium cylinder magnets are often the most practical choice. This cylinder can be used in magnetic assemblies to exactly substitute imperial 1-inch x ½ inch dimensions.

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.
