Assertion : An emf `vec(E)` is induced in a closed loop where magnetic flux is varied. The induced `vec(E)` is not a conservative field.
Reason : The line intergral `vec(E).vec(dl)` around the closed loop is non-zero.

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : An e.m.f. is induced in a closed loop, where magnetic flux is varied. Reason : The line integral vecE. vec(dl) around the closed loop is non-zero.

To induce an e.m.f. in a coil, the magnetic flux

(A): The electric field induced due to changing magnetic field is non-conservative. (R): The line integral of the electric field along a closed loop is always zero.

Consider a conducting circular loop placed in a magentic filed as shown. When magnetic field changes with time, magentic flux also changes and emf is induced. e=-(dphi)/(dt) If resistance of loop is R then induced current. i=e/R For Current, charge must have come into motion. Magnetic force cannot make the statinoary charges to move. Actually there is an induced electric field in the conductor caused by changing magnetic flux, which make the change to move intvec(E).dvec(l)=e=-(dphi)/(dt) This induced electric field is non-electrostatic by nature. line integral of vec(E) around a closed path is non-zero A square non- conducting loop 20 cm on a side is placed in a magnetic field The centre of side AB coincides with the centre of magnetic field The magnetic field is increasing at the rate of 2T/s. Find the magnitude of line integral of induced electric field along path BC.

Asseration: The induced emf in a conducting loop of wire will be non zero when it rotates in a uniform magnetic field. Reason: The emf is induced due to change in magnetic flux.

Asseraton: The work done by a charge in a closed (induced) current carrying loop is non-zero. Reason: Induced electric field is non-conservative in nature.
