Explain the principle of operation of a DC generator.

In an electric DC generator on a steel armature, there are several windings of insulated wire, the ends of each of the windings are connected to two contact plates of the collector. The anchor of the machine is set in rotation due to the action of external forces. When the frame rotates in a magnetic field, a voltage is created at the ends of the turns, which is removed with the help of brushes.
