Neodymium Disc Magnet – 10mm x 2mm | N52
The Neodymium Disc Magnet – 10mm x 2mm | N52 is a premium rare earth permanent magnet that delivers exceptional magnetic strength in a slim, low-profile design. Manufactured from N52 grade neodymium iron boron (NdFeB), this high-performance disc magnet offers one of the strongest commercially available standard magnetic grades, making it ideal for applications where maximum holding power is required within a compact footprint.
Measuring 10mm in diameter and 2mm thick, this magnet is perfect for projects that require a discreet yet powerful magnetic solution. Its thin profile allows it to be easily recessed into timber, plastic, acrylic, metal, and other materials, making it suitable for product manufacturing, magnetic closures, displays, electronics, crafts, and precision engineering applications.
The magnet is axially magnetised through its 2mm thickness, positioning the north and south poles on the two 10mm diameter circular faces. This magnetisation direction creates a concentrated magnetic field across the largest contact surface, providing excellent face-to-face attraction and reliable holding performance against suitable ferrous materials.
Finished with a durable nickel-copper-nickel (Ni-Cu-Ni) coating, the magnet features a polished silver finish that helps protect the neodymium core from corrosion and everyday wear while providing a professional appearance.

Why Choose an N52 Neodymium Disc Magnet?
The N52 grade is recognised as one of the highest standard grades of neodymium magnet, offering exceptional magnetic energy density in a compact size. This allows designers and manufacturers to reduce the overall size of assemblies without sacrificing magnetic performance.
The 10mm x 2mm dimensions provide an excellent balance between holding strength and a discreet profile. Its large diameter relative to its thickness creates a generous magnetic contact area, making it particularly effective for magnetic closures, mounting systems, display fixtures, and applications where the magnet needs to remain largely hidden from view.
Because this magnet is magnetised through its thickness, the magnetic field is concentrated across the two flat circular faces. This configuration delivers excellent holding power when mounted directly against steel surfaces and is well suited to face-to-face magnetic coupling and positioning applications.

Please Note
Neodymium magnets are extremely powerful for their size and should be handled carefully. Although compact, this N52 disc magnet can attract nearby steel objects or other magnets suddenly, creating pinch hazards and potentially causing the magnet to chip if allowed to collide with hard surfaces.
Actual holding force depends on the thickness, grade, finish, and condition of the mating steel surface. Air gaps, paint, coatings, 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 crack the magnet or damage its protective nickel coating.
Keep away from children, pacemakers, medical implants, magnetic storage media, credit cards, 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.
