An electric motor converts electric energy into mechanical energy that can be used to do work. In the experiment we first use DC current to flow through the wire. Remember that DC current flows in only one direction unless there is a switch to reverse its direction.
2.) How Motors Work. Electric motors can be powered by alternating (AC) current or direct current (DC). DC motors were developed first and have certain advantages and disadvantages. Each type of motor works differently but they all use the power of the electromagnetic field.
