if earth is a magnet and there are conductors moving in it why do we not get a current from them, seeing as it is a conductor moving in a magnetic field

If you refer to conductors standing on the Earth's surface, such as the Eiffel Tower, then it is because these conductors are at rest with respect to Earth's magnetic field.

If you refer to a conductor that is moving, such as all metallic parts of a car, I believe that in fact there are induced currents but they are very small because the magnetic field is very weak.
