Question

Assertion :An electric field $\overrightarrow{E}$ is induced in a closed loop where magnetic flux is varied.The induced $\overrightarrow{E}$ is not a conservative field Reason: The line integral $\overrightarrow{E}.\overrightarrow{dl}$ 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. Assertion is incorrect but Reason is correct

Answer 1

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

According to Maxwell's Equation, $\int \overrightarrow{E}.d\overrightarrow{l}=-\int \frac{\delta B}{\delta t}.dt$

Since magnetic field is changing inside the loop, the right hand side of the equation is non-zero. Thus $\int \overrightarrow{E}.d\overrightarrow{l}$ is non zero. Thus the induced $\overrightarrow{E}$ is not a conservative field.
