The plates of a flat capacitor have the shape of disks of radius R. The distance between the disks is d R. The space between them is filled with a homogeneous dielectric with dielectric and magnetic permeabilities e and m. The capacitor is connected to the alternating current circuit I = I0coswt. Neglecting edge effects, determine the ratio of the maximum magnetic energy in the capacitor to the maximum electrical energy.
