KVPY SA Exam 2016 Question Paper

The diagram below shows two circular loops of wire (A and B) centred 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 ${\mathit{l}}_{\mathit{B}}$ 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,
