Question

Answer on this sheet (can use the back). Show all work in an orderly and legible manner. Use appropriate units and significant figures. Work on this alone A strong lightning bolt can carry a current of 200.0 kiloamps if one treats such a bolt as a long thin current-carrying vertical wire calculate the magnitude of the magnetic field produced by the bolt at a distance of 25 meters If two such bolts which are 25 meters vertically apart strike the ground simultaneously what was the magnetic force per meter exerted by one bolt on the other? a) b)

Explanation / Answer

B = ?oI/2?r

B = (4? X 10-7)(200000)/(2?)(25)

B = 1.6 mT

Part B)

Apply F/l = ?oI1I2/2?r

F/l = (4? X 10-7)(200000)(200000)/(2?)(25)

F/l = 320 N/m
