Lenz's law is a manifestation of which fundamental conservation principle?

  1. Conservation of energy
  2. Conservation of mass
  3. Conservation of momentum
  4. Conservation of charge
Show answer and solution

Correct answer: A. Conservation of energy

If induced current aided the flux change, it would self-sustain and grow indefinitely — producing energy from nothing. **So the opposing direction is forced by energy conservation.**
