A 40-loop circular coil has a radius of 10.0 cm. It is placed in a magnetic field so that the field lines from a parmanent magnet (B) are normal to the area of the coil. If the magnet is brought toward the loop so its magnetic field varies from 0.2 T to 0.70 T in 2 microsecond, the induced emf through each coil would be 3.95 x 105 v 87.9 x 104 V 2.80 MV O 7.85 kV
