Chapter 25, Problem 49A

To determine

To Explain: TheLenz law and how is consistent with the conservation of energy.

Explanation of Solution

Introduction:

Lenz’s Law gives the direction of the current which induces in any conductor as the result of the change in the magnetic field. The magnetic field is produced due to the electromagnetic induction which is followed with Faraday’s Law in electrodynamics.According to Lenz law, the induced current tends to oppose the cause behind the production of the current.

According to Lenz law the induced current tends to oppose the cause of its production, in order to oppose this some extra work is done which leads to change in magnetic field. This produces more current and the extra effort gets converted into electrical energy.

Conclusion:

Hence, the Lenz law is consistent with the Law of conservation of energy.
