PhysicsEMI/ACInduced Electric FieldHard2 minPYQ_2015

PhysicsHardsingle choice

Assertion : An emf $ε$ 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 $\oint E \cdot d l$ around the closed loop is non-zero.

Options:

Answer:

Solution:

We know $ε = \oint E \cdot d l = - \frac{d ϕ _{B}}{d t}$ As $\oint E \cdot d l \neq = 0$ , the induced electric field is non-conservative in nature.
