Question

Lenz's law obeys.

Answer 1

1. Lenz law states that the induced current always tends to oppose the cause which produces it.
2. So in order to do work against opposing forces, we have to put extra effort.
3. This extra work leads to periodic changes in magnetic flux hence more current is induced.
4. Thus the extra effort is just transformed into electrical energy which is the law of conservation of energy.
5. Hence this law obeys the law of conservation of energy.

Hence, lenz’s law obeys the law of energy conservation.
