    Each of the three parallel wires, A, B and C are carrying current in the direction shown in the figure. The wire B will

    A)  move to the right

    B)  move to the left

    C)  remain stationary

    D)  moved down in the direction of the  current

    Correct Answer: A

    Solution :

                     If conductor carries current in same direction then force between them will be attractive. If conductor carries current in opposite directions, then force between them will be repulsive. Since, both the wires A and C exert forces on wire B towards right, hence the resultant force on wire B will be towards right. Hence, the wire B will move to the right.
