Question:

A square, single-turn wire loop 1.00 cm on a side is placed inside a solenoid that has a circular cross section of radius 3.00 cm, as shown in figure. The solenoid is 20.0 cm long and wound with 100 turns of wire.(a) If the current in the solenoid is 3.00 A, find the flux through the loop.(b) If the current in the solenoid is reduced to zero in 3.00 s, find the magnitude of the average induced emf in theloop.
