If a time varying magnetic field exists in vertically downwards direction in a region A, an electric field is induced in the direction perpendicular to it i.e. in horizontal plane. How to find the direction of the E field in the horizontal plane?What factors decide the direction of the E field? Once in a book I read that the E field lines form closed loops. If that is true practically then what factors decide the center of the closed loop? Or is the E field induced is just randomly directed?
