Magnetic Product Description:
This rare earth cylinder has a diameter of 4mm and a height of 5mm. It has a magnetic flux reading of 5849 Gauss and a pull force of 0.540kg. Its part number is 21055.
Uses for our rare earth cylinder magnets:
This tiny Neodymium Cylinder is popular with hobbyists, model makers, jewellers and costume designers. Cylinder shaped magnets are suited to recessing into surfaces where their narrow magnetic field can attract, hold and position metal items, or other similarly embedded objects, in the correct place. Unlike Discs or Block shaped magnets, the narrow projection of a cylinder's magnetic field means less chance of interference to sensitive areas nearby. This concentrated type of field translates with great benefit in detection devices, warning sensors and security systems, where field sensitivity is vital for reliable and accurate operation.

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.
