Neodymium Disc Magnet – 75mm x 15mm | N38
Delivering exceptional magnetic strength in a robust, compact design, this Neodymium Disc Magnet measures 75mm in diameter x 15mm thick and is manufactured from premium N38-grade NdFeB (Neodymium Iron Boron) rare earth magnetic material. Designed for demanding industrial, engineering, manufacturing, automation, and research applications, this permanent magnet provides outstanding holding power where high-performance magnetic solutions are required.
Neodymium magnets are the strongest commercially available permanent magnets, offering significantly greater magnetic strength than ferrite, Alnico, or samarium cobalt magnets of similar dimensions. The combination of a 75mm diameter and 15mm thickness provides a large magnetic contact area and high magnetic energy, making this magnet ideal for heavy-duty holding, clamping, positioning, mounting, and magnetic separation applications.
This magnet is axially magnetised, meaning the magnetic poles are located on the two flat 75mm diameter faces. This orientation delivers maximum face-to-face holding force when used against a ferrous steel surface or incorporated into custom magnetic assemblies.
The magnet is protected with a durable nickel-copper-nickel (Ni-Cu-Ni) coating, providing excellent resistance to corrosion, oxidation, and everyday wear while maintaining a smooth, polished finish.

Why Choose an N38 Neodymium Disc Magnet?
The 75mm x 15mm N38 Neodymium Disc Magnet offers an excellent balance of magnetic strength, durability, and versatility. Its large diameter provides an extensive contact area, while the 15mm thickness delivers increased magnetic energy for demanding holding and positioning applications. This makes it an excellent choice for industrial equipment, magnetic fixtures, automation systems, and custom engineering projects.
Please Note
This is a high-strength industrial magnet and should be handled carefully to prevent pinch or crush injuries. The powerful magnetic force can cause magnets to snap together unexpectedly or attract nearby ferrous objects with considerable force.
Holding performance is achieved under ideal conditions using a clean, flat, thick ferrous steel surface with full face-to-face contact. Actual magnetic strength will vary depending on the steel thickness, surface finish, air gap, and application.
Keep away from children, pacemakers, implanted medical devices, sensitive electronic equipment, magnetic storage media, and precision instruments. Avoid drilling, machining, excessive heat exposure, or heavy impacts, as these may permanently damage the magnet or reduce its magnetic performance.

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.
