Neodymium Cylinder Magnet 3mm x 5mm N45
Powerful, compact, and highly versatile, this Neodymium Cylinder Magnet measures 3mm in diameter x 5mm in height and is manufactured from premium N45-grade rare earth neodymium. Designed for precision applications where strong magnetic performance is required in a small cylindrical form, this magnet is ideal for electronics, engineering, crafts, prototyping, and custom assemblies.
Finished with a durable NiCuNi nickel coating, this magnet features a smooth polished metallic appearance while offering increased resistance to corrosion and wear. Magnetised through the 5mm height (axially magnetised), it delivers concentrated magnetic strength in a slim and easy-to-integrate profile.
Its compact dimensions make it well suited to magnetic closures, sensor systems, miniature components, model making, lightweight holding applications, and precision engineering projects. Whether you're building prototypes, repairing equipment, or creating custom magnetic solutions, this N45 neodymium cylinder magnet provides dependable strength and professional-grade performance.

Please Note
Neodymium magnets are very 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 on 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.
