What do you use this magnet for?

Suitable for magnetic connections, prototypes, educational setups, and hobby projects. The spherical shape distributes magnetic force evenly; balls snap on from any position and can form chains and figures when using more magnets. On a flat surface, a sphere only touches the steel at one point, so the holding force is lower than that of a disc of the same size. For heavier parts, use multiple magnets or a larger size. Which sphere magnet should you choose?

The holding force was measured under ideal conditions on a flat steel plate; in practice, the actual holding force is lower. Read how holding force is determined.

Safe use

Magnets are not toys and should be kept out of the reach of children. Keep strong magnets away from pacemakers, electronics, and bank cards. Small spheres can be swallowed. If you swallow multiple magnets, they can attract each other in the body and cause serious injury; seek medical attention immediately.
