As shown in the figure, a large round loop of 269 turns and radius 67.0 cm carries a current of I = A small square loop of 31.0 turns and 1.00 cm on a side is placed at the center of the large loop. If the current in the large loop drops to 0.00 A in 0.0470 s, find the induced emf in the small loop. The square loop is small enough that you can assume that the magnetic field in its region is uniform and equal to the magnetic field at the center of the round loop. (μ0 = 4π × 10-7 T ∙ m/A)
