Assertion: An emf E 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 $\oint \bar{E} \cdot \bar{dl}$ around the closed loop is non-zero.

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

If both assertion and reason are true but reason is not the correct explanation of assertion.

If assertion is true but reason is false.

If both assertion and reason are false.

Solution

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

We know

ε = $\oint \bar{E} \cdot \bar{dl}$

= $- \frac{{dϕ}_{B}}{dt}$

As $\oint \bar{E} \cdot \bar{dl}$ ≠ 0

the induced electric field is non-conservative in nature.
