A long solenoid, of radius a, is driven by an alternating current, so that the field inside is sinusoidal: B(t) = B0 cos(ωt) ˆ z . A circular loop of wire, of radius a/2 and resistance R, is placed inside the solenoid, and coaxial with it. Find the current induced in the loop, as a function of time.

Answer:
A long solenoid, of radius a. is driven by alternating current, so that the field inside is Sinusoidal A circular loop of wire, of radius a/2 and resistance R, is placed inside the solenoid, and coaxial with it. Then the amplitude of current induced in the loop as a function of time is Then the value of α is _____.
