Question
Which one of the following laws or principles allows one to determine the direction of an induced current in a conducting loop of wire due to a changing magnetic flux?
Correct Answer
Option A is the correct answer.
Detailed Explanation
While Faraday's law gives the magnitude of the induced emf, Lenz's law specifically provides the direction, based on opposing the change in flux.
Hint
One law gives magnitude, the other gives direction — this question asks specifically about direction.
