Question

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

(a) : The magnetic field arising due to displacement current is non zero everywhere with maximum at the imaginary cylindrical surface connecting peripheries of the plates. This is because the displacement current is strongest there, where the changing electric field is most concentrated.
