Neodymium Cylinder Magnet 2mm x 3mm N45
Small, precise, and impressively powerful for its size, this Neodymium Cylinder Magnet measures 2mm in diameter x 3mm in height and is manufactured from premium N45-grade rare earth neodymium. Designed for compact applications where reliable magnetic strength is essential, this miniature cylinder magnet is ideal for electronics, engineering, crafts, model making, and precision assemblies.
Finished with a durable NiCuNi nickel coating, this magnet features a smooth polished metallic appearance while helping protect against corrosion and wear. Magnetised through the 3mm height (axially magnetised), it delivers concentrated magnetic force in a compact cylindrical profile.
Its ultra-small size makes it perfect for discreet magnetic closures, sensor systems, miniature mechanisms, lightweight holding applications, and detailed fabrication work where space is limited. Whether you're prototyping electronic components, building models, or creating custom magnetic solutions, this N45 neodymium cylinder magnet offers dependable performance in a tiny yet powerful format.

Please Note
Neodymium magnets are extremely strong for their size and should be handled carefully. Small magnets can present a swallowing hazard and must be kept away from children. Avoid allowing magnets to snap together forcefully, as they may chip or crack upon impact.

Surface Treatment
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.
Range and Tolerance
Magnets are readily available in Blocks, Discs, Cylinders & Rings. We 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.
Magnetic Properties
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.
