The Neodymium Disc Magnet – 60mm x 30mm | N48 is an exceptionally powerful rare earth magnet designed for demanding industrial, engineering and specialised magnetic applications. Manufactured from high-performance N48 grade Neodymium Iron Boron (NdFeB), this large cylindrical magnet delivers outstanding magnetic strength relative to its size, making it suitable for applications requiring substantial magnetic attraction and a compact, concentrated magnetic field.

Measuring 60mm in diameter x 30mm thick, this heavy-duty neodymium disc magnet features a substantial cylindrical body and a large circular contact surface. Its combination of diameter, thickness and N48 magnetic grade makes it a powerful magnetic component for industrial assemblies, custom magnetic fixtures, engineering projects, magnetic separation systems and specialised equipment development.

Neodymium magnets, also known as rare earth magnets, NdFeB magnets or super strong magnets, are among the strongest commercially available permanent magnets. They are widely used in manufacturing, industrial automation, engineering, scientific research and magnetic equipment because of their high magnetic energy density.

The N48 magnetic grade identifies the magnetic material's performance classification. Compared with lower grades such as N35 or N38, N48 neodymium material generally provides greater magnetic energy potential for magnets of equivalent dimensions and magnetisation.

However, the N48 grade does not indicate a pull force of 48kg. Actual magnetic holding strength depends on the magnet's dimensions, magnetisation direction, contact area, target steel thickness, surface condition and installation arrangement.

With its large 60mm diameter and substantial 30mm thickness, this magnet can produce extremely strong magnetic attraction and must be handled with exceptional care. Powerful neodymium magnets can attract steel objects or other magnets suddenly, creating serious pinch, crush and impact hazards.
