The 20mm × 3mm Neodymium Disc Strong Magnet is a high-performance rare-earth permanent magnet engineered to deliver exceptional magnetic force in a slim, compact disc form. Constructed from premium neodymium-iron-boron (NdFeB) alloy, this magnet exhibits significantly higher magnetic flux and pulling strength compared to conventional ferrite or ceramic magnets of similar size.
The low-profile disc geometry makes this magnet especially suitable for applications where magnetic strength is required without adding bulk. Its nickel-plated coating improves resistance to corrosion and surface wear, ensuring durability and reliable performance over time in indoor and protected environments.
This strong disc magnet is widely used in robotics fixtures, sensor mounts, magnetic couplings, magnetic holders, DIY electronics, magnetic closures, and educational projects where compact size and powerful holding force are essential. Its uniform magnetic field provides stable and predictable interactions when used in assemblies, mounts, or proximity sensors.
