Dear Harsh,

So the "flux rule" that the emf in a circuit is equal to the rate of change of the magnetic flux through the circuit applies whether the flux changes because the field changes or because the circuit moves (or both).... Yet in our explanation of the rule we have used two completely distinct laws for the two cases  –    \stackrel{\mathbf{v \times B}}{}  for "circuit moves" and   \stackrel{\mathbf{\nabla \ x \ E \  = \  -\part_{\ t} B}}{}   for "field changes".
We know of no other place in physics where such a simple and accurate general principle requires for its real understanding an analysis in terms of two different phenomena.

– Richard P. Feynman,   The Feynman Lectures on Physics
