Magnetic Product Description:
This popular rare earth cylinder has a diameter of 3mm and a height of 4mm. It is an N50 grade rare earth magnet. It has a magnetic flux reading of 6742 Gauss and a pull force of 326g. It is identified by the AMF magnet part number C-D3H4-N50.
Uses for our rare earth cylinder magnets:
This small Neodymium cylinder magnet is axially magnetised, which means the magnetic field is present through the top and bottom flat faces of the cylinder. Neodymium magnet is the strongest form of permanent magnet and has largely replaced traditional magnets such as Alnico, Samarium Cobalt and Ferrite. Rare earth magnets do have their limitations, in particular, they have a more limited operating temperature range and begin to lose strength at a lower temperature than traditional magnets. However, Neodymiums excel in terms of magnetic power and far exceed other forms of magnetic material when it comes to strength to size ratio. There is a range of different coatings available although Nickel plating is the standard and it provides reasonable resistance to corrosion in normal atmospheric conditions.
No FAQ available
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.
