Question

4. Show that Lenz's law is a direct consequence of law of conservation of energy.​

Answer 1

Answer:

Lenz's law is based upon the law of conservation of energy. Lenz law states that the induced current always tends to oppose the cause which produce it. So in order to do work against opposing force we have to put extra effort. This extra work leads to periodic change in magnetic flux hence more current is induced. Thus the extra effort is just transformed into electrical energy which is law of conservation of energy.

Answer 2

In this question, we are asked to show that Lenz's law is a direct consequence of the law of conservation of energy.​

• The law of energy conservation serves as the foundation for Lenz's law.
• According to this law, the induced current always tends to resist the source that generates it.
• Thus, we must use more effort to act against opposing forces.
• More current is induced as a result of the additional work because it causes periodic changes in magnetic flux.
• As a result, the additional effort is simply converted into electrical energy by the law of conservation of energy.
• According to Lenz's law, an induced current always tends to be in opposition to the factor that caused it.
• Therefore, working against an opposing force requires more effort. This additional labor causes a periodic change in magnetic flux, which induces a greater current.
