If your metal car moves over a wide, closed loop of wire embedded in a road surface, will the magnetic field of the earth within the loop be altered? Wil thiis produce a current pulse? What would be an application of this for a traffic intersection?

It might create a current pulse. However it is more reliable to create an AC current in the loop and measure the variation in inductance when a car passes over the loop. This technique is already being used at traffic intersections and on highways.

the sphere is equivalent to that of a bar magnet, yet this similarity is superficial. The magnetic container of a bar magnet, or the different sort of everlasting magnet, is created by skill of the coordinated spins of electrons and nuclei interior iron atoms. The Earth's center, inspite of the incontrovertible fact that, is warmer than 1043 ok, the Curie factor temperature at which the orientations of spins interior iron replace into randomized. Such randomization motives the substance to lose its magnetic container. subsequently the Earth's magnetic container is brought about no longer by skill of magnetized iron deposits, yet frequently by skill of electric powered currents interior the liquid outer center (because it spins, electrons tend to stay in the back of, to that end producing a small cutting-edge). yet another function that distinguishes the Earth magnetically from a bar magnet is its magnetosphere. At great distances from the planet, this dominates the exterior magnetic container. electric powered currents triggered interior the ionosphere additionally generate magnetic fields. this style of container is often generated close to the place the ambience is closest to the solar, inflicting on a daily basis transformations that could deflect floor magnetic fields by skill of as much as a minimum of one degree.

If I understand your question the answer is yes, but only by a negligible amount. I don't know how this could be used for traffic intersections.
