The lenz's law is also a statement of the law of conservation of:

Correct answer: C. Energy

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

Explanation

Lenz's law is also a statement of the law of conservation of energy. It articulates that the direction of the induced electromotive force (emf) or current in a circuit opposes the change in magnetic flux, which is a practical application of the principle of energy conservation.

About Lenz's Law

Lenz's law states that the induced current flows in a direction that opposes the change in magnetic flux producing it. Questions connect this rule with Faraday's law, magnetic flux, induced emf and the direction of motion or current, while distinguishing opposition to flux change from opposition to the magnetic field itself.
