Full Definition of MOBILE
: a construction or sculpture frequently of wire and sheet metal shapes with parts that can be set in motion by air currents; also: a similar structure (as of paper or plastic) suspended so that it moves in a current of air
Abstract sculpture that has moving parts, driven either by motors or by the natural force of air currents. Its revolving parts create a new visual experience of constantly changing volumes and forms. The term was initially suggested by Marcel Duchamp for a 1932 Paris exhibition of such works by Alexander Calder, who became the mobile's greatest exponent.
