View · Overview

Product overview

These 10 x 1 mm N42 neodymium disc magnets provide a very wide contact face while taking up minimal depth. Their axial magnetisation places the poles on the flat sides, and the NiCuNi coating gives a smooth finish for indoor craft, scenery and modelling work.

This geometry is intended for flat lids, box closures, removable scenery panels and broad flaps where there is plenty of surface area but almost no room to drill deeply. The wide footprint spreads the attraction across the joint, helping a panel close evenly instead of pivoting around a narrow point. Sideways shear is an estimate of approximately 80 g. It is a useful format for layered card, thin board and shallow model parts where a thicker disc would stand proud or remove too much supporting material.

Use a 10 mm drill and cut the recess to 1.2 mm deep. For a 3D-printed component, start with a 10.1 mm hole. Because the magnet is only 1 mm thick, the base of the socket must be level and free from raised glue that could tilt the disc. Press it flat while the adhesive takes, confirm polarity before enclosing it inside a lid or card layer, and avoid leaving the magnet proud of the surrounding surface. Supplied in packs of 1, 10, 25, 50 and 100.

Notes · Q & A

Which magnet size should I choose for miniatures?

A 2×1 mm disc suits infantry weapon swaps, while 3×1 mm is a practical step up for arms and small components. Sizes around 3×2 to 5×2 mm work well for basing and larger parts, with 5×3 mm and above better suited to vehicles, large models and army transport. Each listing includes a calculated pull figure in grams so you can compare sizes on the same basis.

What does the N42 magnet grade mean?

The grade describes the magnetic material: at identical dimensions, a higher number generally produces more pull. N52 is typically around 20–25% stronger than N42 at the same size, but increasing the magnet's diameter or thickness usually makes a larger practical difference than changing grade alone. Our range is clearly specified as N42.

How do I keep the polarity consistent?

Before separating the stack, mark one face with a permanent marker and use that mark as your polarity reference. Dry-fit every pair before applying adhesive, and glue the two halves while the magnets are still attracting each other in the intended orientation. Reversing one magnet is one of the most common magnetisation mistakes.

What size hole should I drill for a magnet?

Use a drill matching the magnet diameter; for a designed 3D-printed socket, allow roughly 0.1 mm extra diameter. Make the recess approximately the magnet thickness plus 0.2 mm for adhesive so the face can sit level with the surrounding surface. CA adhesive is suitable for fixing these magnets into plastic, resin or metal parts.

How should neodymium magnets be handled safely?

Swallowing two or more magnets can cause serious internal injury, so keep loose magnets away from children and use them only for adult hobby work. Neodymium magnets are also brittle and may chip if allowed to snap together. Bring them together slowly from the edge rather than letting their flat faces strike each other.
