Strong N52 Neodymium Disc Magnets 2mm x 1mm, 100 Pack NiCuNi - Micro Round Rare Earth Magnets for Wargaming Miniatures, 3D Printing and Small Closures Review (2026)

Size and where it fits

These magnets measure 2 millimeters in diameter by 1 millimeter thick, based on the Amazon product listing, which is among the smallest sizes commonly sold for miniature magnetizing rather than the more common 3 millimeter or larger sizes used for general weapon swaps. That smaller footprint matters for parts that are too thin or narrow to accept a bigger magnet without a drilled hole showing through the material or weakening a slim part like a wrist joint, small hand-held weapon, or other fine component found on smaller scale miniatures. Builders working on parts too delicate for standard 3 millimeter magnets have fewer size options to choose from, which is the main reason to reach for a micro magnet pack like this one instead of a general purpose set.

N52 grade in a tiny package

The listing specifies N52 grade neodymium, which is the strongest commercially available grade of neodymium magnet, and using that top grade at such a small size is meant to claw back some holding strength that a micro magnet would otherwise lack compared to a larger magnet of a lower grade. Even so, magnetic pull force scales down substantially with magnet volume, so a 2 by 1 millimeter N52 disc will never hold as firmly as a larger magnet regardless of grade, and builders should treat this pack as suited to lightweight parts rather than as a universal weapon-swap solution across an entire miniature collection.

NiCuNi coating and pack size

The magnets carry a NiCuNi, or nickel-copper-nickel, plated finish, which is the standard protective coating used on neodymium magnets since the bare metal itself is prone to corrosion and flaking without it. This coating helps the magnets hold up to repeated handling and press-fit installation into drilled holes without the surface chipping away over time. The pack includes 100 magnets, which is a substantial supply for magnetizing many small parts across a collection of miniatures, since this size is typically used for one detail at a time rather than as the primary magnet for larger, load-bearing joints on a model.

Uses beyond miniature weapon swaps

Because of their small size, these magnets are also suited to tasks outside strict weapon magnetizing, including securing small 3D printed parts together, creating tiny magnetic closures on cases or boxes, or other craft applications where a larger magnet would be visually obvious or physically too big to hide. This versatility is a byproduct of the size rather than a feature specific to this listing, but it is worth knowing for anyone buying a pack mainly for miniatures who might also use leftover magnets on other small projects around a hobby desk.

Practical handling drawbacks

At just 2 millimeters across, these magnets are easy to drop and difficult to find again once they land on a carpeted floor or cluttered desk, which is a common complaint with micro magnets of this size in general rather than something specific to this brand. Working over a tray or light-colored surface, and handling them with tweezers rather than fingers, reduces the chance of losing several magnets during a single gluing session. Builders should also expect the small holding power to limit use to lightweight resin or plastic parts, since heavier metal components or larger weapon arms are more likely to pull free from a magnet this size over time.
