This Neodymium cylinder magnet weighs 1 gram and has a pull force 0.2080kg. It is nickel-coated, is 2.5mm in height, with an outside diameter of 2.50mm. Gauss 6351, Grade N48, direction of magnetization through height.
Neodymium cylinder magnets are widely used in sensors, reed switches, meters, holding applications, and medical devices. These magnets can be magnetized either along their length or across their diameter. Due to their shape, they generate a magnetic field with an extended reach, making them particularly useful in various applications. You’ll find cylinder magnets in acrylic signage, picture frames, joinery, mining, engineering, construction, lighting and educational settings.
These strong neodymium cylinders are perfect for applications requiring Imperial measurements, as their dimensions are exactly 1/4" in height and diameter. The unique properties of cylinder magnets affect both their magnetic power and their applications. The magnetic poles are located on the flat end surfaces, with the length of the cylinder concentrating the pull force into a narrow, penetrating magnetic field. This directional pull force is advantageous for applications demanding precision and a targeted hold.
The magnetic strength of these rare earth cylinder magnets depends significantly on their dimensions, particularly the thickness or depth of the magnetic material.
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.
