Question:

Case : Read the passage and answer the question(s).

Lenz's Law states that the polarity of induced EMF is such that it tends to produce a current which opposes the change in magnetic flux that produced it. Hypothetically or not, assume that on approaching the magnetic north pole towards a coil, the coil develops current in clockwise direction. 

Which of the following is true?

Options:

This violates conservation of charge.

This violates conservation of energy.

This violates conservation of angular momentum.

This does not violate anything.

Correct Answer:

This violates conservation of energy.

Explanation:

Lenz's Law is in agreement with conservation of energy and the given statement violates Lenz's Law.
