007 10.0 points A bolt of lightning, such as the one shown on the left in the figure, behaves like a vertical wire conducting electric current. As a result, it produces a magnetic field whose strength varies with the distance from the lightning. A 108-turn circular coil with a radius of 0.835 m is oriented perpendicular to the magnetic field...
