As the armature rotates through the magnetic field of the poles, voltage is generated. The ends of the armature loop are connected to a split ring called a commutator. Brushes contact the commutator and wires connect the brushes to a load. Since the circuit is complete, current will flow. Wires are wound around the magnetic poles and attached to the brushes, ensuring stronger current and proper flow. The wiring is called the field circuit of the generator.
