Pack of 20 black neodymium magnets

This pack contains 20 LOVIMAG neodymium-iron-boron magnets finished in a black triple-layer coating. Each magnet measures .47in by .47in and is designed for whiteboards, refrigerators and other ferromagnetic surfaces. They suit home, office, classroom and workshop organisation tasks.

Holding strength and surface protection

The rare-earth material lets a single magnet hold 17 or more sheets of A4 paper or 30 plus sticky notes on a vertical whiteboard. The three-layer paint, nickel and copper coating resists corrosion and reduces the risk of scratching the mounting surface during daily repositioning.

Upgrading from standard fridge magnets

These replace weaker ceramic or flexible magnets that struggle with multi-page documents or thicker card stock. The jump is worth it when you need reliable hold for layered paperwork, project plans or heavier items without increasing the magnet footprint. Buyers who need larger diameters or higher pull forces for structural work will need a different product.

Questions about this item

How do I attach these 0.47in neodymium magnets to a whiteboard without damaging the surface?

Place each magnet gently against the board and let the magnetic force pull it into position; do not slide or bang them, as the strong NdFeB field can scratch the coating if dragged across the surface.

Will the three-layer black paint, nickel and copper coating need reapplication over time?

The triple coating is designed to resist corrosion for the life of the magnet under normal indoor use; no recoating is required unless the surface is physically scratched or chipped.

At what point will holding more than 17 sheets of A4 paper cause the magnets to slip?

Each magnet is rated to hold up to 17 sheets of A4 paper; exceeding that load reduces the safety margin and the magnets may release under vibration or door slams.
