A parallel plate capacitor made of circular plates is being charged such that the surface charge density on its plates is increasing at a constant rate with time. The magnetic field arising due to displacement current is:Non-zero everywhere with maximum at the imaginary cylindrical surface connecting peripheries of the plates

In a plane electromagnetic wave travelling in free space, the electric field component oscillates sinusoidally at a frequency of 2.0 x $10^{10}$ Hz and amplitude 48V $m^{-1}$ . Then the amplitude of oscillating magnetic field is: (Speed of light in free space = 3 x $10^8$ $ms^{-1}$ )

When light propagates through a material medium of relative permittivity $\varepsilon_r$ , and relative permeability $\varepsilon_r$ , the velocity of light, v is given by (c - velocity of light in vacuum)
