A loop of wire and a bar magnet are moving relative to one another. Which motion in the diagrams shown below will NOT induce a current in the loop?
Lenz's Law: A changing magnetic field can induce a current in a direction that produces its own magnetic field that opposes the change.
Faraday's Law: A mathematical expression of Lenz's law that states the induced voltage is minus the rate of change of magnetic flux with respect to time.
The Attempt at a Solution
It is very clear that A, B, and C all have a changing magnetic flux since the field gets stronger as the magnet gets closer to the loop.
In D the angle of loop is changing, and since flux only counts the number of magnetic lines perpendicularly cutting the plane, as the loop rotates the flux changes.
So the answer is E by process of elimination. Yet in E doesn't the flux change too, since the magnet is getting closer? How does spinning the loop affect the change in flux?
I researched a bit and think it might have something to do with faraday's paradox but I did not understand it.
