Assertion : An emf is induced in a closed loop when magnetic flux is varied. The induced electric field E is not a conservative field. Reason : The line integral E d l around the closed loop is non-zero.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIfboth assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and reason is the correct explanation of assertion.

Step-by-step solution

We know = E d l =- d _B d t As E d l 0 , the induced electric field is non-conservative in nature.
