The diagram below shows two circle 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 `I_(B)` in loop B as shown. Possible actions which we might perform on loop A are:
ltbegt (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.

Options

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

Answer
