In which of the following will a current NOT be induced in the conducting loop?
a. Magnet moving toward upright conducting loop of wire
b. Magnet moving away from an upright conducting loop of wire
c. Magnet moving toward a horizontal conducting loop of wire
d. Conducting loop of wire rotating in front of magnet
e. Magnet rotating in front of conducting loop of wire
2. The attempt at a solution
I eliminated d because the loop is being rotated and that should trigger induced current, right?
a, b, and c seem like they would have induced current because the loop is moved into or out of the magnetic field, with either the magnet moving.
So I know that when the loop is rotated, there is induced current, but is that the same for a rotated magnet? If a rotated magnet does not trigger induced current, then would e be the correct answer?
