In a lightning bolt, a large amount of charge flows during a time of 1.4 x 10-3 s. Assume that the bolt can be represented as a long, straight line of current. At a perpendicular distance of 37 m from the bolt, a magnetic field of 7.8 x 10-5 T is measured. How much charged has flowed during the lightning bolt?
