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.

A powerful bolt of lightning can carry a current of 225 kA. (a) Treating a lightning bolt as a long, thin wire, calculate the magnitude of the magnetic field produced by such a bolt of lightning at a distance of 91 m. (Answer in µT) (b) If two such bolts strike simultaneously at a distance of 25 m from each other, what is the magnetic force per meter exerted by one bolt on the other? (Answer in N/m)

Problem 4 The bolt of lightning depicted in the figure below passes 230 m from a 135-turn coil oriented as shown. If the current in the lightning bolt falls from 6.10 X 106 A to zero in 10.9 us, what is the average voltage induced in the coil? Assume the distance to the center of the coil determines the average magnetic field at the coil's position. Treat the lightning bolt as a long, vertical wire and ignore the 200 m...
