This problem requires calculations in three dimensions and will familiarize you with the details of the magnetic field made

by a solenoid (a long coil).

A solenoid of length L = 0.5 meter and radius R = 3 cm is wound with N = 50 turns of wire carrying a current I = 1 ampere.

Its center line lies on the x axis, with the origin at the center of the solenoid (Figure 18.98).

(d) How do the magnitude and direction of the magnetic field outside the solenoid compare to the magnitude and direction of the magnetic field inside the solenoid?
