The charge on a parallel plate capacitor varies as $q = q_0 \cos(2\pi \nu t).$ The plates are very large and close together (area $= A,$ separation $= d$). The displacement current through the capacitor is

$A$ cylindrical region contains a uniform electric field that is along the cylinder axis and is changing with time. If $r$ is the distance from the cylinder axis,the magnitude of the magnetic field within the region is:

Which equations are called Maxwell's equations?

The existence of electromagnetic waves was experimentally confirmed by
