Lenz's law says the induced current opposes the change in:
AMagnetic flux
BMagnetic force
CMagnetic field
DMagnetic focus
Answer & Solution
Correct answer: A. Magnetic flux
1. The law fixes the direction of the induced current.
2. The induced current opposes the change in magnetic flux that produced it.
3. So the correct answer is magnetic flux.
