Question:

Consider a system consisting of two concentric solenoids, as illustrated in FIGURE 22-62. The current in the outer solenoid is I1 = 1.25 A, and the current in the inner solenoid is I2 = 2.17 A. Given that the number of turns per centimeter is 105 for the outer solenoid and 125 for the inner solenoid, find the magnitude and direction of the magnetic field

(a) Between the solenoids and

(b) Inside the inner solenoid.
