What is this magnet used for?

Small and light: 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 be used to form chains and figures with more balls. On a flat surface, a ball touches the steel at only one point, so the holding force is lower than that of a disc of the same size. In jewelry, only use it if it is concealed and not against the skin: the NiCuNi layer contains nickel. Which ball magnet should you choose?

The holding force is 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 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 medical attention immediately.
