Neodymium Disc Magnet – 12mm x 7mm | N50 Rare Earth Magnet
The Neodymium Disc Magnet 12mm x 7mm | N50 is a premium rare earth permanent magnet engineered to deliver outstanding magnetic strength in a compact and versatile disc shape. Measuring 12mm in diameter and 7mm thick, this magnet is manufactured from N50-grade Neodymium Iron Boron (NdFeB), one of the highest-performance magnetic materials available, making it ideal for industrial, commercial, engineering, and DIY applications.
With its high magnetic energy product, the N50 grade provides exceptional holding power for its size, making this magnet suitable for applications where maximum strength is required while keeping components compact. Whether used in manufacturing, automation, electronics, magnetic fixtures, cabinetry, product design, or research, this magnet delivers reliable, long-lasting performance.
This magnet is axially magnetised, meaning the north and south poles are located on the two flat 12mm diameter faces. This provides maximum face-to-face holding force when attached to a ferrous steel surface or paired with another magnet.
The magnet is finished with a durable nickel-copper-nickel (Ni-Cu-Ni) coating, which protects against corrosion, oxidation, and everyday wear while providing a smooth, polished appearance suitable for both industrial and consumer applications.

Why Choose an N50 Neodymium Disc Magnet?
The 12mm x 7mm N50 Neodymium Disc Magnet offers an excellent combination of high magnetic strength, compact dimensions, and long-term durability. The N50 grade provides greater magnetic performance than many standard neodymium grades, allowing designers and engineers to achieve strong magnetic holding power without increasing the size of their assembly.
Its 7mm thickness also provides greater magnetic field depth than thinner disc magnets, making it well suited to applications requiring improved holding force through small air gaps or thicker mounting materials. This makes it an excellent choice for magnetic clamping, positioning systems, industrial equipment, and precision engineering.

Please Note
This is a powerful rare earth magnet and should be handled with care. Strong neodymium magnets can snap together unexpectedly and may cause pinch injuries or chip if allowed to collide.
Holding force is measured under ideal conditions using a clean, flat, thick mild steel surface with direct face-to-face contact. Actual performance will vary depending on the material, surface finish, air gap, mounting method, and operating environment.
Keep away from children, pacemakers, implanted medical devices, sensitive electronic equipment, and magnetic storage media. Do not drill, machine, or strike the magnet, as neodymium is hard but brittle and may crack or shatter if subjected to impact. Avoid prolonged exposure to temperatures above the recommended operating limit for standard N50 neodymium magnets, as excessive heat may permanently reduce magnetic strength.

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.
