The figure below shows a cross-section of a long (infinite for our purposes) solenoidal system consisting of two coaxial solenoids, of radii a=4.3 cm and b=28.1 cm. These solenoids have the same number n=20 cm-1 of the turns of the wire per unit length. The wire is common and fed by the time t-dependent current I(t)=Io.sin(21f.t) but in the opposite directions as illustrated in the figure. Here the current amplitude lo=20.5 A and frequency f=148 Hz. In this problem, we...
