According to Lenz's law of electromagnetic induction, the direction of the induced electromotive force is such that it always opposes the very cause that produces it. Which fundamental conservation law does this phenomenon directly reflect?

💡 Solution & Explanation

Lenz's law is a direct consequence of the law of conservation of energy because mechanical work must be done to move a magnet against the opposing magnetic field created by the induced current, which then appears as electrical energy. If it aided the cause, perpetual motion machines would become possible. Michael Faraday formulated the main laws of electromagnetic induction.
