You're driving at 95 km/h in a direction 35 degrees east of north, in a region where the earth's magnetic field of 5.5x10^-5 T is horizontal and points due north. If your car measures 1.5m from tis underbody to its roof, calculate the induced emf between roof and underbody. (You can assume the sides of the car are straight and vertical.) Is the roof of the car at a higher or lower potential than the underbody?
