Which cube magnet do you choose?
A cube magnet is a neodymium magnet with six flat sides. This makes it ideal when you want to place magnets tightly next to or on top of each other, for example on a magnetic board, in a model or in a closure. Choose based on the holding force and the space you have. Use the calculator below or the Magnet Advisor if you want to know how much holding force your application requires.
Quickly choose by application
| Application | Size | Holding force (approx.) |
|---|---|---|
| Model making and small figures | 3 x 3 x 3 mm | 390 g (N50) |
| Magnetic boards and light closures | 5 x 5 x 5 mm | 980 g (N45) |
| Closure mechanisms and prototypes | 10 x 10 x 10 mm | 5.5 kg |
| Technical applications | 12.7 x 12.7 x 12.7 mm | 9.6 kg |
| Heavier closures and workshop use | 15 x 15 x 15 mm | 12 kg |
All sizes are available in the cube magnet collection: 3, 4, 5, 6, 7, 8, 10, 12, 12.7 and 15 mm.
Calculate how much holding force you need
Enter the weight, the number of cube magnets and the surface. The calculator shows the minimum holding force required per magnet and displays suitable cube magnets from our range. This is a guideline: always test with one or two magnets.
Cube or block?
A cube is equal in all directions, while a block has a length, width and height. If you have a long or flat opening, choose a block magnet. If you have little space but want a lot of force, a cube is compact and powerful.
What to pay attention to
- Holding force: the values are measured under ideal conditions on a flat steel plate. Read how holding force is determined.
- Quality: the 3 mm cube is available in N35 and N50. N50 has more holding force at the same size. The 5 mm cube is available in N35, N45 and N52 (the stated holding force is for N45).
- Temperature: all cube magnets are rated up to 80 °C.
- Safety: small cubes can be swallowed; if you swallow several magnets, they can attract each other inside the body and cause serious injury. Larger cubes can snap together hard; keep your fingers away.
