Magnetic Product Description:
This neodymium magnetic cylinder has a diameter of 12mm and a height of 20mm. It has a magnetic flux reading of 6034 Gauss and a pull force of 5.8 kilos against 3mm mild steel. It is identified by the AMF magnet part number 21019.
Uses for our rare earth cylinder magnets:
Neodymium Cylinder magnets vary in length and diameter but they all project a similar magnetic field that is strong, narrow and penetrative. Assemblies that contain cylinder shaped magnets can harness and direct this power to produce simple and maintenance-free technologies. These can be found in consumer electronics, sensor and metering devices and magnetic couplings that can transmit kinetic energy without direct contact via gears or differentials or breaching sealed barriers. Magnetic attraction is used in remote mixing for medical and pharmaceutical research and water-tight, sealed underwater propulsion systems, This futuristic and frictionless method of propulsion bypasses the need for shafts, seals and bearings that are consumable components and that are the areas prone to failure in these more traditional drivetrain systems.

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.
