Answer is : Electric motor
An electrical generator or Dynamo :A device that converts mechanical energy into electrical energy is called an Electric Generator.
An electric motor is an electrical machine that converts electrical energy into mechanical energy.
An inductor, also called a coil or reactor, is a passive two-terminal electrical component which resists changes in electric current passing through it.
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification.
