A square, single-turn wire loop e = 1.00 cm on a side is placed inside a solenoid that has a circular cross section of radius r = 3.00 cm, as shown in the end view of the figure below. The solenoid is 21.0 cm longand wound with 80 turns of wire.(a) If the current in the solenoid is 4.00 A, what is the magnetic flux through the square loop?T.m2(b) If the current in the solenoid is reduced to zero in 4.00 s, what is the magnitude of the average induced emf in the square loop?
