What do you use this magnet for?

Small and lightweight: suitable for model making, creative constructions, educational setups, and small prototypes. The spherical shape distributes the magnetic force evenly; balls click together from any position and can form chains and figures with more balls. On a flat surface, a ball only touches the steel at one point, so the holding power is lower than that of a disc of the same size. In jewelry, only use it if concealed and not against the skin: the NiCuNi layer contains nickel. Which sphere magnet should you choose?

The holding power was measured under ideal conditions on a flat steel plate; in practice, the actual holding power is lower. Read how holding power 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 balls can be swallowed. If multiple magnets are swallowed, they can attract each other inside the body and cause serious injury; seek immediate medical attention.
