A
It opposes the change in magnetic flux that produced it.
B
It enhances the change in magnetic flux that produced it.
C
It has no effect on the magnetic flux.
D
It is always aligned with the magnetic field direction.
Correct Answer
Option A
Detailed Explanation
Lenz's law states that the polarity of the induced emf is such that it tends to produce a current which opposes the change in magnetic flux that produced it, as described in the provided context.
