Question

Two concentric circular coils X and Y of radii 16cm and 10 cm,respectively,lie in the same vertical plane containing the north to south direction, coil X has 20 turns and carries a current of 16 A;coil Y has 25 turns and carries a current of 18 A.The sense of the current in X is anticlockwise,and clockwise in Y,for an observer looking at the coils facing west.Give the magnitude and direction of net magnetic field due to the coils at their center.
