Question

Prove theoretically, the relation between e.m.f induced and rate of change of magnetic flux in the electric circuit in e.m.i.

Answer 1

Gauss's Law. The total of the electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux through an area is defined as the electric field multiplied by the area of the surface projected in a plane perpendicular to the field.
