Near San Francisco, where the vertically downward component of the earth's magnetic field is 4.7 10-5 T, a car is traveling forward at 26 m/s. The width of the car is 1.7 m.
(a) Find the emf induced between the two sides of the car.
(b) Which side of the car is positive—the driver's side or the passenger's side?
