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 as shown. The magnetic field at the coil drops from 4.30 x 10 3 T to 0.00 T in 10.5...
