State Amperes circuital law.

State Ampere's circuital law, expressing it in the 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.

State Ampere's circuital law and express it mathematically. Give the sign convention involved in the relation.

Explain how Biot-Savart's law enables one to express the Ampere's circuital law in the integral form , viz., oint vecB .vec(dl) = mu_0 I where I is the total current passing through the surface.
