If a conductor moves within a uniform constant magnetic field, the magnetic force would separate the charges leading to an induced emf. And if the conductor was stationary, and the magnetic field were to change,from Maxwell's equations I understood that there would be a nonelectrostatic electric field that would yield the to the induced emf.
What if the conductor moved, and the exterior magnetic field was varying with time(increasing/decreasing). Is motional emf in it's basic form valid?
