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