    When a load is added, like turning on the windshield wipers, the alternator incurs a counter torque. In order to maintain the same vehicle speed, more fuel must be burned. The alternator output current results in a torque which opposes the torque from the engine through the belt. This is an example of Lenz' law. Induced quantities are oriented in an opposite direction to the original quantities, i.e. torque, flux, current/mmf, voltage/emf.
