Lessons in practical electricity; principles, experiments, and arithmetical problems, an elementary text-book . Fig. 251.—Angular Currents Tend to Become Parallel and Flow in the Same Direction. ELECTR OD YNAMICS. 285 of this coil, being free to move, dip into two cups of mercury,located one above the other along the axis of the coil. Con-nections are made as indicated, so that the two coils are inseries when connected to an external circuit. The planes ofthe coils should be at right angles to each other. When thecurrent flows through both coils, the movable coil tends toturn, according to Law 2 for angular currents. The force measured is the force which must be applied tokeep the movable coil at right angles against the turning effort.
