...the circuit is defined to be unit electromotive force. The expression m (ca, — <a) is equivalent to the change in the number of lines of force passing through the circuit in the positive direction.

...plane is parallel to the lines of force. But the strength of the current depends upon the rapidity of the change in the number of lines of force passing through the coil. If the lines of force represented in Fig. 260 are examined, it will be seen that the number of lines... ## Physics by Experiment: An Elementary Text-book for the Use of Schools
