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?
Options
A Lenz's law
Correct Answer
B Gauss' law
C equivalence principle
D Faraday's law
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.
