Answer to Problem 90P
The
Explanation of Solution
The path for the ampere’s law is rectangular. The magnetic field inside the solenoid is uniform and parallel to the axis of the solenoid. For the two sides of the rectangle which is perpendicular to the axis of the solenoid has magnetic field perpendicular to it for the portion it is inside the solenoid and for the portion outside the solenoid the magnetic field is zero. Thus
For the side which is outside the solenoid, the magnetic field is zero, thus
