A parallel-plate capacitor , made of two circular plates of radius R = 10 cm, is being charged. What is the magnitude of the induced magnetic field induced by the displacement current between the plates of the capacitor at a distance r = 2 cm from the axis of the plates at a time when the electric field varies at the rate dE/dt = 2 × 1012 V/m s?
