What is this magnet used for?

Small but strong: suitable for model making, sensors and electronics projects, small displays, and hidden closures in boxes and small hatches. In jewelry, only use when embedded and not against the skin: the NiCuNi layer contains nickel. Too small for cabinet doors or panels; choose a larger size for those applications. 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.
