MEALOS 300pcs 3x1mm Tiny Magnets

MEALOS offers a foundational set of tiny magnets ideal for delicate Warhammer 40k projects. Each magnet measures 3×1 mm, which is small enough for discrete placements on miniatures and accessories. The kit contains 300 magnets, providing ample quantity for multiple models or extensive basing work. The magnets are described as durable with a reliable pull for their size, which helps secure weapons, shields, or decorative elements without visible gaps. A provided rod magnet can assist with placement and polarization accuracy, reducing the chance of misalignment during assembly.

For modelers who frequently magnetize small parts, these magnets offer a practical balance of size and strength. They’re especially suitable for fine weapon exchanges or detaching specific kit components without stressing the miniature. The storage case included helps keep magnets organized and easy to access during painting and assembly. As with all micro magnets, ensure the magnet’s polarity is correctly oriented to prevent unexpected detachment during gameplay. Overall, this set delivers reliable micro magnets for 40k-scale modeling projects.

BEST CHOICE MAGNETS 240 Pack

This 240-pack from Best Choice Magnets delivers a more robust option for Warhammer 40k basing and weapon swapping. Each magnet measures 5×2 mm, a common size that provides substantial holding power without being visually intrusive on a small model. The set emphasizes durability, with materials resistant to demagnetization, corrosion, and oxidation—important for models that undergo frequent handling during hobby sessions. The magnets’ smooth surfaces also reduce the risk of scratching the model’s paint job during installation or adjustment.

The 5×2 mm magnets strike a practical balance for many 40k builds, enabling effective attachment for arms, shields, or alternative weapon configurations without demanding overly large components. The pack’s quantity is well-suited for several squads or a mixed-bag of basing accessories. While these magnets are stronger than micro options, users should still test fit and polarization before committing to final placements. The product supports flexible design strategies for dynamic poses and modular transportation of miniatures.

The Army Painter Miniature & Model Magnetic Pieces

The Army Painter offers a two-size magnet set designed for changing weapons and other magnetic modifications on models. With 5 mm magnets for larger attachment points and 3 mm magnets for finer work, this kit supports modular weapon swapping and equipment changes on Warhammer 40k miniatures. The magnets are praised for strong performance, enabling quick swaps during tabletop deployment without the need for glue or permanent attachments.

For players who want quick changes to arm configurations or easily detachable basing elements, this set provides a straightforward solution. The dual-size approach allows for a range of applications—from swapping close combat weapons to adjusting ranged options—without compromising miniature integrity. As always, verify correct polarity and clean mating surfaces to maximize hold and minimize paint wear over time.

Small Magnets, 120 Pack 10x2mm

This 120-pack from Best Choice Magnets features magnets sized at 10×2 mm, offering a stronger hold for medium-scale attachments on Warhammer 40k models. The material is described as durable with resistance to demagnetization, corrosion, and oxidation, which helps maintain performance across frequent handling and play. The larger surface area of 10×2 mm can be advantageous for heavier components or where a more pronounced magnetic contact is beneficial for stability during transport or gaming.

The pack’s variety supports multiple project scenarios—basing pieces, weapon racks, or detachable components. While the magnets are sturdier, modelers should still test fit, polarity, and spacing to avoid interference with miniature painting or sculpted details. The smooth, easy-to-disassemble design minimizes surface scratches on surfaces such as boards or display stands.

tElement Tiny Disc Magnets 1/16×1/32 Inch

tElement’s smallest magnets are ultra-compact 1/16 inch diameter by 1/32 inch thick, around 1.6 mm by 0.8 mm. Their tiny size makes them ideal for extremely delicate Warhammer 40k pieces, fine basing details, and micro-modularity where larger magnets would be intrusive. The N52 grade indicates high strength for their size, enabling secure mounting on small resin or metal components.

These tiny magnets support high-precision work, such as securing tiny accessory bits, swapping arms on miniature figures, or aligning modular dioramas. Because of the diminutive scale, careful polarity checks and precise placement are essential to achieve reliable magnetic connections without visible hardware. Their ultra-compact profile complements intricate basing and display options for competitive 40k builds.

Buying Guide: Key Purchase Considerations for Warhammer 40k Modeling

• Magnet size and strength: Balance magnet dimensions with the weight and surface area of the component. Larger magnets provide stronger holds but may be visually intrusive on small models.
• Polarity consistency: Mark magnet orientations to prevent polarization errors that can cause components to detach during gameplay or transport.
• Material durability: Choose magnets with resistance to corrosion and demagnetization, especially for models that will be handled often or exposed to humidity.
• Surface protection: Opt for magnets with smooth surfaces to minimize paint wear and scratching on miniature surfaces or bases.
• Modularity goals: Decide between mono-use magnets (one strong hold) or multi-magnet sets (different sizes for weapon swaps, basing, or display options).
• Ease of use: For beginners, kits with clear polarization guides or included placement tools can reduce frustration during assembly.
• Cost per magnet: Higher quantities often reduce per-magnet cost, but ensure you’ll use the full set to avoid waste.
• Application safety: Handle neodymium magnets with care to prevent pinching injuries and protect sensitive model paints during handling.

When selecting magnets for Warhammer 40k, consider the scale of your projects, the frequency of weapon or piece swaps, and how often you transport or display your models. A combination of micro magnets for fine detail and medium-sized magnets for sturdier attachments can cover most hobby scenarios. Always test fit on a spare model or an inconspicuous area before committing to permanent placements on a prized miniature.
