Lenz's law is a direct consequence of the law of conservation of which physical quantity?
- A.Charge
- B.Energy
- C.Momentum
- D.Mass
Show correct answer & step-by-step solution
Correct answer: B — Energy
Solution
Lenz's law states that the direction of the induced current is such that it opposes the change in magnetic flux that produced it. This ensures that work must be done to move a magnet, which is consistent with the law of conservation of energy.
