A powerful bolt of lightning can carry a current of 225 kA.
(a) Treating a lightning bolt as a long, thin wire, determine the magnitude of the magnetic field produced by such a bolt of lightning at a distance of 93 meter.
__________?µT
(b) If two such bolts strike simultaneously at a distance of 13 meter from each other, find the magnetic force per meter exerted by one bolt on the other?
___________?N/m
