suppose there is a region S through which the magnetic field changes with time then is the electric field induced there only or everywhere in space .
if everywhere what equations does it satisfy

Both ampere"s and Faraday's laws relate to electrical and magnetic fields that change in intensity as per time. Gauss's electrical law relates to a change in electrical intensity as per distance. The time variable equations relate to photons, while Gauss's equation describes charged particles (mass). If the intensity of the magnetic field was time variable in the form of a sphere, it would produce the electric field in radii directions (Gauss law).

going by maxwell
curl of E =- time differential of B
so if at a point there is no change of B then curl is 0 considering nearby point E should also be 0
