Question

Does Lenz's law violate the law of conservation of energy? Justify your answer

Answer 1

1. No, it does not violate the law.
2. Lenz's law obeys the law of conservation of energy in the case of electromagnetic induction.
3. The mechanical source energy spent in opposing the motion of the magnet (or the coil) is transformed into electrical energy of the coil due to which current flows through it.
4. Hence the total energy remains conserved
