Question

The diagram below show two circular loops off wire $\left(AandB\right)$ centered on and perpendicular to the $x-axis$, and oriented with their planes parallel to each other. The $y-axis$ passes vertically through loop $A$ (dashed line ). There is a current $I_b$ in loop $B$ as shown. Possible actions which we might perform on loop $A$ are
(i) Move $A$ to the right along $x$ axis closer to $B$.
(ii)Move $A$ to the left along $x$ axis away from $B$
(iii) As viewed from above, rotate $A$ clockwise about $Yaxis$
(iv) As viewed from above, rotation $A$ anticlockwise about $Yaxis$
Which of these actions will induce a current in $A$ only in the direction shown.

• A. Only (i)
• B. Only(ii)
• C. Only (i) and (iv)
• D. only(ii) and (iii)

Answer 1

The correct option is A Only (i)
