Q23: A truck is carrying a steel beam of length 15.0 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 25.0 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 com- ponent of the Earth’s magnetic field at this location has a magnitude of 35.0 mT. What is the magnitude of the induced emf between the ends of the beam?
