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.
Simply put, an electric motor can be defined as a machine that converts electrical energy into mechanical energy. The first electric motors date back to 1740s when Scottish monk Andrew Gordon created electrostatic devices.s mentioned, the electric motor relies on electromagnetism. Upon placement of a coil carrying current (rectangular coil) in a magnetic field, a torque is generated that acts on the coil and forces it to rotate continuously.
