a part of the energy supplied to the circuit by thegenerator is expended on the field, and the current does notinstantly rise to its full value even in a straight wire. Againwhen the current is broken this field closes in again on the con-ductor and yields up its energy, thus maintaining the… … Fig. 400. with an annature pivoted so that it may swing to and fro infront of the poles with a short amplitude between stops.
