A lightning bold strikes the ground 200m away from a 100 turncoil. Suppose that the radius of the coil is .8 m and that thecurrent carried by the lightning bolt is 6.0 MA and falls to zeroin .0105s. What is the induced emf in the coil if it is orientedwith its normal along the magnetic field direction? If the wire hasa cross sectional area of 7 x 10-7 m2(diameter of wire is .001m) and it is made out ofcopper ( Ï=1.7 X 10-8 Ωm), what is the magnitude and directionof the induced current in the wire?
