Final answer:
The emf induced between the two sides of the car is zero due to the orientation of the magnetic field and the car's movement direction.
Step-by-step explanation:
To find the electromagnetic force (emf) induced between the two sides of the car, we can use Faraday's Law of electromagnetic induction. Faraday's Law states that the emf induced in a conductor is equal to the rate of change of magnetic flux through the conductor. In this case, the magnetic field is vertical and the car is moving horizontally, so there won't be any change in magnetic flux. Therefore, the emf induced between the two sides of the car will be zero.
