In a lightning bolt, a large amount of charge flows during a time of 2.1 10-3 s. Assume that the bolt can be treated as a long, straight line of current. At a perpendicular distance of 30 m from the bolt, a magnetic field of 7.8 10-5 T is measured. How much charge has flowed during the lightning bolt? Ignore the earth's magnetic field.

007 10.0 points A bolt of lightning, such as the one shown on the left in the figure, behaves like a vertical wire conducting electric current. As a result, it produces a magnetic field whose strength varies with the distance from the lightning.
