tions per minute has a frequency /= 2ioo X4=l6o. (e) An electromotive force of self-induction is set up in acircuit counter to the changing current caused to flow inthe circuit. This counter E.M.F. is the result of thevarying lines of force, set up by the variable current,which thread the adjacent… … Fig. 23. of the induced E.M.F., whether of self-induction or ofmutual induction, is, according to Lenzs law, in thedirection to oppose the inducing force. This must alsofollow from the law of the conservation of energy;otherwise any empty circuit, say the secondary of a trans-former, would absorb…
