part b and c please

symmetries. 1. Solenoid: The magnetic field inside a very long solenoid must be along the axis of the solenoid. The magnetic field outside the solenoid is approximately zero. A very long solenoid of radius b carries a current I with turns per length. We want to use Ampere's law to find the magnetic field at a point P a distance ? from the central axis. Assume r<b so point P is inside the solenoid. a. To take advantage of the symmetry, we choose the Amperian loop to be a rectangle. The rectangle must extend outside the solenoid to enclose current. We need to introduce a height H to make a closed loop but H must not be in the final answer. We will calculate $5 ds at one leg at a time. i. What is the integral 5 ds along the left leg of the Amperian loop, i.e., outside the solenoid? ii. What is the integral 5 ds along the top and bottom horizontal legs of the Amperian loop?
