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)
