Grade: N50 – high neodymium for maximum performance
Coating: NiCuNi (Nickel-Copper-Nickel) for durability and corrosion resistance
Magnetisation: Axial (magnetised through the height)
Surface Gauss: 6801 Gauss
Part Number: 21064
Applications:
Thanks to its small size and strong magnetic output, this neodymium cylinder magnet is perfect for:
Electronics and sensor assemblies.
DIY projects and prototyping.
Craft, hobby, and model-making applications.
Magnetic closures and fastening solutions.
Industrial and engineering uses requiring compact magnets.
Why Choose This Magnet?
The N50 grade ensures a powerful magnetic field, allowing this small cylinder magnet to perform reliably in demanding applications. Its axial magnetisation means the magnetic poles are located on the flat circular faces, making it ideal for vertical pull or direct contact applications.
Despite its strength, care should be taken when handling. Neodymium magnets are brittle and can chip or crack if allowed to snap together or collide with metal surfaces.
Whether you're working on intricate electronics or need a dependable small magnet for everyday use, this 2.7mm x 4mm neodymium cylinder magnet offers the perfect balance of size, strength, and durability.

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.
