GK QUESTION#2980
Which law explains that the induced electromotive force (EMF) in a circuit is directly proportional to the rate of change of magnetic flux through it?
Show Answer
Answer
A. Faraday’s Law
Show Explanation
Explanation
Faraday’s law relates induced emf to the rate of change of magnetic flux linkage. For a fixed number of turns, the emf magnitude increases with the magnitude of the flux-change rate; the direction is accounted for by Lenz’s law.
