The displacement current has (literally) far reaching consequences One thing we immediately notice is that the laws of electricity and
magnetism are now more symmetrical* Faraday’s law of induction states
that there is an induced emf equal to the rate of change of magnetic flux Now, since the emf between two points 1 and 2 is the work done per unit
charge in taking it from 1 to 2, the existence of an emf implies the existence
of an electric field
