What is this magnet used for?

Suitable for light components and precision work: model making and dioramas (removable roofs and hatches), small closures for boxes, and sensor setups. For jewelry, only use when concealed and not against the skin: the NiCuNi layer contains nickel. Too small for objects that bear weight or are frequently pulled. Which disc magnet should you choose?

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