A lightning bolt produces a rapidly varying magnetic field. If the bolt strikes the earth vertically and acts like a current in a long straight wire, it will induce a voltage in a loop aligned like that shown in the figure below. What voltage is induced in a 0.90 m diameter loop 60.0 m from a 2.00x106 A lightning strike, if the current falls to zero in 25.0 us? (Discuss circumstances under which such a voltage would produce noticeable consequences.)...
