Rare Earth Magnet Cube 2.5mm N42 Neodymium

Rare Earth Magnet Cube 2.5mm N42 Neodymium for Hobby and Craft

Tiny project, big problem? When you need a magnet that's strong enough to do real work but small enough to vanish inside a build, generic fridge magnets just won't cut it. This 2.5mm N42 neodymium rare earth magnet cube delivers serious holding power in a footprint smaller than a peppercorn.

Hobbyists know the frustration of weak magnets sliding around, breaking in half, or losing strength after a few months. This precision-machined N42 grade cube is rated for high coercivity and long-lasting magnetism, with a nickel-copper-nickel triple coating to resist corrosion and chipping. Use it for mineral and gem testing, jewelry clasps, model railroads, miniature mechanisms, science classroom demos, or detecting ferrous content in metal samples. The cube shape means stable face-to-face contact and predictable polarity — exactly what makers, engineers, and prospectors actually need.

Key Features

• Premium N42 grade neodymium for strong, lasting magnetism in a tiny form factor
• Precision 2.5mm cube — fits where larger discs and bars can't
• Triple-coated finish resists corrosion, chipping, and oxidation
• Ideal for prospecting, mineral testing, jewelry, micro-electronics, and crafts
• Flat faces give reliable surface contact and clean alignment
