The Dynamo is a machine for the production of an electric current by the use of mechanical force. We have seen that whenever the lines of magnetic force are cut by a conductor, a galvanometer coupled to the ends of the conductor shows the presence of an electric current. In a dynamo there must be a magnetic field to furnish the lines of force, conductors in which the induction takes place, and a means of moving the conductors across the lines of force. This motion sets up an electromotive force at the ends of the conductors, and by coupling these ends to an external circuit a current is obtained.
