An electric motor is a device which converts electrical energy into mechanical energy 

Parts of the Motos 

Armature Coil: Consists of a single coil of insulated copper wire in the form of a rectangle. It is supported in such a way that it can spin freely. It is arranged in such a way that it lies directly in between two permanent or strong magnets. 

Strong Magnets: The armature is placed between 2 strong field magnets which provide a strong magnetic field
