In the very useful form called the shunt dynamo, the wire wound on, the field magnets is a long coil of small wire coupled to both brushes as a shunt to the external circuit. If the resistance of the external circuit increases, less current passes in that circuit, more current passes through the shunt, and the magnetism of the field is increased, causing the E. M. F. of the machine to rise. If the resistance of the external circuit decreases, the E. M. F. of the dynamo falls.
