Which instrument is used in converting electrical energy into mechanical energy?

An Electric motor converts electrical energy into mechanical energy. The main point here to note is that a current has its magnetic field. Working:-

•Inside the motor there is a conductor wire placed between fixed strong magnets.

•When current is provided to the electric motor the wire inside the motor get magnetised due to flow of current.

•These wires are already placed in strong magnetic field of a strong magnet.

•This cause a repulsion between the wire and the strong magnets. This repulsion cause movement of wire. The direction of movement is determined by Fleming's left hand rule.

Electric motor is use for doing very mechanical works. It has a very widespread application like in fan, car, etc.
