3mm Disc Magnets

3mm N52 neodymium disc magnets in multiple thicknesses, from 0.5mm to 3mm. One of the most-used hobby diameters — covering 28mm wargaming bases, jewellery clasps, FPV drone hatches, MagSafe-compatible accessories, model railway reed-switch installs, and small 3D-printed enclosures.

Want a different shape at this diameter — spheres, cylinders, countersunk discs, rings, or blocks? Browse our massive library of N52 magnets in every shape.

Each listing shows exact thickness, pull force, and pack size. All magnets ship from our US warehouse.
