These N48 neodymium cube magnets measure exactly 0.25 x 0.25 x 0.25 inches (1/4 x 1/4 x 1/4 in / 6 x 6 x 6 mm) — a compact square form that grips securely from any of its six faces. Strong fridge magnets for kitchen and home office, these cubes hold several sheets of paper or a notepad flat on a refrigerator door or pegboard panel without sliding. On a whiteboard or steel filing cabinet, the smooth NiCuNi surface won't scratch the finish even after repeated use.
Because every face carries equal field strength, there is no wrong orientation. That matters when you want to hang a picture on a wall nail without piercing the frame — press the cube against the nail head and place the frame over it. It matters equally when building a flat grid array for a STEM field visualization or force-balance demonstration, stacking cubes column by column without any piece flipping out of sequence. For craft and hobby closures, the equal-face geometry means faster placement — no flipping to find the right pole as with disc magnets.
N48 rare earth grade delivers up to 5 lbs pull force per piece — meaningfully stronger than the N35–N42 baseline for this size. The NiCuNi triple-layer coating resists corrosion, keeps all six faces non-abrasive, and is rated to 176°F (80°C). Each magnet is magnetized axially through one face pair, giving a defined north and south pole for projects where orientation matters: sensor placement, multi-magnet assemblies, prototyping fixtures. At 0.25 inches on every side — roughly the size of a sugar cube — small enough to arrange in tight groups, substantial enough to handle without tweezers.
The 27-piece pack covers a kitchen, home office, and classroom without reordering; every piece pulls the same as the first one you try.
These magnets can snap together suddenly and chip. Keep away from pacemakers and implanted electronic devices. Store away from hard drives, credit cards, and sensitive electronics. Not suitable for children under 14.
