State Ampere's circuital law, expressing it in integral form.

(a) State Ampere's circuital law, expressing it in the integral form. (b) Two long coaxial inlsulated soenoids, S_(1) and S_(2) of equal lengths are would one over the other as shown in the figure. A steady current ''I'' flows through the inner solenoid S_(1) to the other end B, which is connected to the outer solenoid S_(2) through which the same current ''I'' flows in the opposite direction so as the come out at end A. If n_(1) and n_(2) are the number of turns per unit length, find the magnitude and direction of the net magnetic field at a point (i) inside on the axis and (ii) outside the combined system.
