A car has a vertical radio antenna 1.05 meters long. The car travels at 5.80 m/s on a horizontal road where Earth's magnetic field is 50.0 mT, directed horizontally toward the north. The car is moving due east. Calculate the magnitude of the induced emf (voltage). (1 mT = 1 microTesla = 1x 106 Tesla.)

A truck is carrying a steel beam of length 15.0 m on a free-way. 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 north-ward while the length of the beam maintains an east-west orientation. The vertical component of the Earths magnetic field at this location has a magnitude of 35.0 T. What is the magnitude of the induced emf between the ends of the beam?

A truck is carrying a steel beam of length 15.0 in 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 component of the Earths magnetic field at this location has a magnitude of 35.0 T. What is the magnitude of the induced emf between the ends of the beam?
A 2.00-m length of wire is held in an eastwest direction and moves horizontally to the north with a speed of 0.500 m/s. The Earths magnetic field in this region is of magnitude 50.0 T and is directed northward and 53.0 below the horizontal. (a) Calculate the magnitude of the induced emf between the ends of the wire and (b) determine which end is positive.
To monitor the breathing of a hospital patient, a thin belt is girded around the patients chest as in Figure P20.21. The belt is a 200-turn coil. When the patient inhales, the area encircled by the coil increases by 39.0 cm2. The magnitude of Earths magnetic field is 50.0 T and makes an angle of 28.0 with the plane of the coil. Assuming a patient takes 1.80 s to inhale, find the magnitude of the average induced emf in the coil during that time. Figure P20.21
