This popular rare earth cylinder has a diameter of 3mm and a height of 3mm. It is an N50 grade rare earth magnet. It has a magnetic flux reading of 6480 Gauss and a pull force of 317g. It is identified by the AMF magnet part number C-D3H3-N50.
This neat little magnet is equal in height and diameter which can be very convenient when calculating spacing and means of attachment. They may be mini magnets in size however they are super strong neodymium with a N50 grade magnetic material; the second highest strength of magnet available. Rare earth cylinder magnets are popular for all sorts of commercial products including electric motors, security sensors and speakers. The narrow field that extends from the faces of the rod magnet means they are well suited to complex manufacturing equipment where moving parts need to be guided with accuracy. These magnets are silver in appearance due to the Nickel plating which provides the magnetic material with some corrosion resistance.

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.
The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
