This Experiment/ Demonstration was created to present the basic ideas behind a DC electric motor and its applications in our daily life.  Also, the counterpart of the motor, which is known as a generator is introduced in this demonstration.

Electric motors involve moving or rotating coils of wire which are driven by electric current producing magnetic force that opposes the magnetic field. They transform electrical energy into mechanical energy.

Generator does the opposite of what a motor does.  When a coil of wire is moved or rotate in a magnetic field, it would produce current.  Generators transform mechanical energy into electrical energy.
