Exercise 5 A solenoid with N = 1000 turns, of length L = 3.0 m and circular section with radius rs = 10 cm, is traversed by a constant current Is = 10 A. An electric circuit approximating a square coil of side 2.0 cm and overall resistance R = 3.0 Omega is located inside the solenoid. Let 0-30° be the angle between the axis of the solenoid and the normal to the circuit. Calculate: a) the mutual inductance Msc between solenoid and circuit. At a certain instant of time the current in the solenoid, constant up to that moment, begins to decrease exponentially with a time constant 7 = 10 s. Considering the self-induction of the circuit to be negligible, calculate: b) the trend over time of the induced current Ic(t) on the circuit and its maximum value Inx; c) the mechanical moment M acting on the circuit as a function of time and its maximum value Max
