Question

Assertion :An emf $\overrightarrow{E}$ is induced in a closed loop where magnetic flux is varied. The induced $\overrightarrow{E}$ is not a conservative field. Reason: The line integral $\overrightarrow{E}\cdot d\overrightarrow{l}$ around the closed loop is nonzero.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

A and R is true and R explains A. According to Faraday's law of electromagnetic induction.
$\int \overrightarrow{E}\cdot d\overrightarrow{l}=\frac{d\varphi }{dt}$
So, $\left(E\right)$ is non-conservative field as in conservative field line integral over a closed loop is zero.
