Neodymium Cylinder Magnet – 6mm x 6mm | N38
The Neodymium Cylinder Magnet – 6mm x 6mm | N38 is a compact rare earth permanent magnet designed for reliable magnetic performance across a wide range of industrial, commercial, electronic, and DIY applications. Manufactured from premium N38 grade neodymium iron boron (NdFeB), this precision cylinder magnet offers an excellent balance of magnetic strength, durability, and affordability.
Measuring 6mm in diameter and 6mm in length, this magnet features a symmetrical cylindrical profile that is easy to integrate into precision assemblies, automation equipment, sensors, electronic devices, magnetic fixtures, and custom product designs. Its equal diameter and length provide a balanced magnetic field while maintaining a compact footprint suitable for confined spaces.
The magnet is axially magnetised through its 6mm length, placing the north and south poles on the two circular end faces. This magnetisation direction produces a concentrated magnetic field, making the magnet ideal for magnetic holding, positioning, reed switch activation, sensing, alignment, and magnetic coupling applications.
Protected by a durable nickel-copper-nickel (Ni-Cu-Ni) triple-layer coating, the magnet offers excellent resistance to corrosion and everyday handling while maintaining a bright silver finish. Whether you're manufacturing products, designing prototypes, repairing equipment, or developing custom engineering solutions, the 6mm x 6mm N38 Neodymium Cylinder Magnet provides dependable long-term performance.

Why Choose an N38 Neodymium Cylinder Magnet?
The N38 grade offers dependable magnetic performance while providing a cost-effective solution for a wide range of engineering and manufacturing applications. It is an excellent choice when strong magnetic force is required without the higher cost of premium grades.
The 6mm x 6mm dimensions create a balanced cylindrical shape that is easy to install into drilled holes, housings, shafts, and compact assemblies. Its equal diameter and length make it suitable for magnetic locating, positioning, holding, and sensing applications where consistent performance is essential.
Because the magnet is magnetised through its length, the magnetic field is concentrated on the circular end faces. This configuration provides reliable end-to-end attraction and makes the magnet ideal for magnetic switches, couplings, fixtures, and precision engineering assemblies.

Please Note
Neodymium magnets are extremely powerful for their size and should always be handled carefully. This 6mm x 6mm N38 cylinder magnet can attract nearby steel objects or other magnets unexpectedly, creating pinch hazards and potentially causing the magnet to chip or crack if allowed to collide.
Actual holding force depends on the thickness, finish, and condition of the mating steel surface. Air gaps, paint, coatings, rust, uneven contact, elevated temperatures, and sideways or peeling forces can significantly reduce magnetic performance.
Neodymium magnets are hard but brittle. Do not drill, cut, machine, weld, or subject the magnet to heavy impacts, as this may damage the magnet and its protective coating.
Keep away from children, pacemakers, medical implants, magnetic storage media, and sensitive electronic equipment that may be affected by strong magnetic fields.

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.
