A bolt of lightning strikes the ground 200 m from a 100-turn coil oriented vertically and with the plane of the coil pointing toward the lightning strike. The radius of the coil is 0.800 m and the current in the lightning bolt falls from 6.02 × 106 A to zero in 10.5 ?s. What is the voltage induced in the coil over this time period? [A question for future electrical engineers: is there any way
to get lightning to strike repeatedly at the same point?]
