In a lightning bolt, a large amount of charge flows during a time of 2.2 10-3 s. Assume that the bolt can be treated as a long, straight line of current. At a perpendicular distance of 28 m from the bolt, a magnetic field of 7.3 10-5 T is measured. How much charge has flowed during the lightning bolt? Ignore the earth's magnetic field.
I thought I had to solve for I using B = mu*I/2pi*r and then figure out the current but I am stuck now. Please help
