sition 2 where the flu,x threadingthe coil is zero, in a time of t seconds,then the average rate of change offlux is (j)/t lines per sec. The c.g.s. unit of e.m.f. is thatgenerated in a coil of one turn whenthe flux threading the coil is chang-ing at the rate of one line per sec.The practical unit,… … the e.m.f. at any instant = -tt 10volts. Fig. 12.—Generation of elec-tromotive force. Right HandRule: thumb—motion; fore- That portion of the coil wherein the fiSpMiectromot^liorel^e.m.f. is actually induced is the con-ductor xy which cuts the lines of force, and the quantity d<f>/dt isthe…
