Lenz's law is based on:
Correct answer: D. Law of conservation of energy
- A. Law of conservation of current
- B. Law of conservation magnetization
- C. Law of conservation of charges
- D. Law of conservation of energy
Explanation
Lenz's Law is a fundamental principle in electromagnetism. It states that when there is a change in the magnetic field through a conductor, an electromotive force (EMF) is induced in the conductor, which creates a current that opposes the change in magnetic field. This law is based on the principle of conservation of energy and is used to explain phenomena such as electromagnetic induction and the behavior of electric motors and generators. It's a pretty fascinating concept.

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.
