MCQ
A current carrying infinitely long wire is kept along the diameter of a circular wire loop, without touching it. The correct statement $(s)$ is (are) :

$(A)$ the emf induced in the loop is zero if the current is constant.

$(B)$ The emf induced in the loop is finite if the current is constant.

$(C)$ The emf induced in the loop is zero if the current decreases at a steady rate.

$(D)$ Theemf induced in the loop is finite if the current decreases at a steady rate.

  • $(A,C)$
  • B
    $(B,D)$
  • C
    $(B,C)$
  • D
    $(A,D)$

Answer

Correct option: A.
$(A,C)$
a
$(\phi)_{\text {luep }}=0$ for all cases

so induced emf $=0$
