A truck is carrying a steel beam of length 18.0 m on a freeway. An accident causes the beam to be dumped off the truck and slide horizontally along the ground at a speed of 23.0 m/s. The velocity of the center of mass of the beam is northward while the length of the beam maintains an east-west orientation. The vertical component of the Earth's magnetic field at this location has a magnitude of 48.0 µT. What is the magnitude of the induced emf between the ends of the beam?
