Faraday's law of induction. A square loop of single-turn wire of side I = 1.2 cm is placed inside a solenoid having a circular cross section of radius r = 3.12 cm, as shown in end view in the figure. The solenoid is 20 cm long and has 200 turns of wire. (a) If the current in the solenoid is 3.00 A, what is the magnetic flux through the square loop? (b) If the current in the solenoid is reduced to zero in 3.00 s, what is the magnitude of the average electromotive force induced in the square loop?
