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.

A

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

B

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

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A

`DeltaW=q(DeltaV)`
Here `DeltaV=` non-zero in a closed loop.

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.
