Magnetic Product Description:
This neodymium cylinder has a diameter of 11mm and a height of 30mm. It has a magnetic flux reading of 6197 Gauss and a pull force of 5.1kgs against 3mm mild steel. It is identified by the AMF magnet part number 21021.
Uses for our rare earth cylinder magnets:
This is a very typical cylinder-shaped magnet, sometimes called a Rod magnet. The height is a far greater dimension than the diameter, which defines the cylinder shape. These thin Neodymium cylinders have highly concentrated magnetic fields at each end, one North and one South. The cylinder shape by nature projects a deep and narrow field of attraction that can be exploited in practical ways in a range of situations and devices. Small diameter cylinders are used in detecting the presence of invisible ferrous material through other surfaces, or used in the activation of alarms or warning systems when ferrous or other magnetic materials enter its field range. Neodymium Magnets are permanent with no moving parts and perform these tasks consistently and without fail in almost any atmospheric conditions and unimpacted by dust or grime. This makes them ideal for security, monitoring and alarm 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.
