by increasing the rate at which theselines are cut—that is, the speed; and (3) by increasingthe length of the conductor—that is, the number of turnsof wire. 264. The Induction Coil is a simple and effective devicefor producing induced currents of very high electro-motiveforce, by increasing the… … Fig. 186.—Induction coil. circuit contains a current-interrupter, for rapidly mak-ing and breaking the current, and so inducing a rapidsuccession of inverse and direct currents. It acts uponthe same principle as the interrupter used with the elec-tric bell. (See Fig. 166,/.) The coil is generally…
