The diagram below shows two circle loops of wire (A and B) centred on and perpendicular to the $\mathrm{x}$-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 y axis (iv) As viewed from above, rotate A anticlockwise about y axis Which of these actions will induce a current in A only in the direction shown.

• Correct answer
  A

  Only (i)
• B

  Only (ii)
• C

  Only (i) and (iv)
• D

  Only (ii) and (iii)

Hence, the correct answer is option: 'A'.
