MCQ

A circular loop of wire is in the same plane as an infinitely long wire carrying a constant current $i$. Four possible motions of the loop are marked by $N, E$, $W$, and $S$ as shown below. A clockwise current is induced in the loop when loop is pulled towards

A
$N$
✓
$E$
C
$W$
D
$S$

✓

Answer

Correct option: B.

$E$

b
(b)

Magnetic field linked with loop is downwards.

When loop is pulled away from wire, flux linked with loop decreases. This induces a current in loop which tries to oppose this change (in accordance with Lenz's law).

So, current induced in loop is clockwise.
