Question

Lenz's law is a consequence of the law of conservation of

• A. Energy
• B. Momentum
• C. Mass
• D. Charge

Answer 1

Answer:

A. Energy

• Lenz's law states that the direction of the induced current in a conductor is such that it opposes the change in magnetic flux that caused it. • This opposition requires external work to be done to maintain the change in flux (e.g., moving a magnet), and this work is converted into the electrical energy of the induced current. • Therefore, Lenz's law is a direct application of the principle of conservation of energy.
