A square, single-turn wire loop 1.00 cm on a side is placedinside a solenoid that has a circular cross section of radius 3.00cm. The solenoid is 20.0 cm long and wound with 100turns of wire.
(a) If the current in the solenoid is3.00 A, find the flux through the loop.
(b) If the current inthe solenoid is reduced to zero in 3.00 s, find the magnitude of the average induced emf in the loop.
