Maxwell`s Equations (4)
... whether induction can occur in the opposite sense; that is, can a changing electric flux induce a magnetic field? The answer is that it can; furthermore, the equation governing the induction of a magnetic field is almost symmetric with the above equation. We often call it Maxwell's law of induction ...
