Lenz's law states that the induced current direction is such that it:
AAids the change in flux
BOpposes the change in flux
CIs always clockwise as seen from front
DVanishes after one cycle
Answer & Solution
Correct answer: B. Opposes the change in flux
1. Lenz's law: induced current OPPOSES the change in magnetic flux producing it.
2. This is a consequence of energy conservation — otherwise we'd build a perpetual-motion device.
3. The minus sign in Faraday's law mathematically encodes Lenz's law.
