Hint for Ch. 30, special problem

[short solenoid]

Go to a point P located a distance x away from the center; choose infinitesimally thin bands of the solenoid and treat as circular current loops. Span the solenoid with bands from z = -(L+x) to +L-x and thereby integrate the contributions to B at a distance z away from the center of each infinitesimal current ring.
