A 40-loop square coil has a side length of 10.0 cm. It is placed in a magnetic field so that the field lines from a permanent magnet (B) are normal to the area of the coil. If the magnet is brought toward the loop so its magnetic field varies from 0.20 T to 0.70 T in 2 microsecond, the induced emf through each coil would be Group of answer choices 3.9 x 105 V 2.80 MV 2.5 kV 8.9 x 104 V
