Question

Which of the following statement is valid?

• A. Lenz’s law is a consequence of the law of conservation of energy
• B. Lenz’s law is a consequence of the law of conservation of momentum
• C. Lenz’s law is a consequence of the law of conservation of force
• D. Lenz’s law is a consequence of the law of conservation of mass

Hint:

Lenz's law helps ensure that the energy in electromagnetic systems is conserved by opposing changes in magnetic flux.

Answer 1

The Correct Option is A

Step 1: Understanding Lenz's Law
Lenz's law states that the direction of the induced current in a conductor is always such that it opposes the change in magnetic flux that produced it.
This is a manifestation of the conservation of energy, as it ensures that the energy involved in electromagnetic induction is conserved.
Step 2: Why Other Options are Incorrect
Option (b) is incorrect because Lenz’s law is not directly related to the conservation of momentum.
Option (c) is incorrect because Lenz’s law is not related to the conservation of force.

Option (d) is incorrect because Lenz’s law is not concerned with the conservation of mass.

Step 3: Conclusion
Thus, Lenz’s law is a consequence of the law of conservation of energy.
