If the induced current did not oppose the change, one could get:
AFree energy
BMore flux
CLess heat
DZero emf
Answer & Solution
Correct answer: A. Free energy
1. The text tests Lenz's law by assuming the opposite.
2. The magnet would then be pulled in and speed up on its own.
3. That would give energy for nothing, which is impossible.
4. So the answer is free energy.
