Electromagnetic Induction: Solenoid

Q- A solenoid has length L = 30 cm, radius 6 cm, and N1 = 5500 turns; its axis coincides with the z-axis. A circular conducting loop containing N2 = 15 turns of radius a = 3 cm is centered inside the solenoid; the plane of the loop makes a 30° angle with respect to the z-axis. The loop has a net resistance of R = 0.015 W. The current in the windings of the solenoid is varying with time according to the expression I1(t) = 0.35 A + 0.75 (A/s) t. Calculate the induced current in the loop at t = 4 s.
