Problem 2: (Displacement) current in a charging capacitor d A more realistic model of a charging capacitor consists of two thin metal disks of radius R sep- I I arated by a distance d < R and attached at their centers to thin charging wires stretching off to infinity in both directions. As the capac- R itor charges, a steady current I flows along the charging wires and a surface current K(s) flows to 0 out/in along each disk in such a way that the surface charge density o on the disk is uniform at any moment in time and zero at t = 0. (a) Find the electric field between the plates as a function of t, and thereby obtain the displacement current density ſa (b) Use symmetry to argue that the magnetic field halfway between the plates points in the direction (around the axis of symmetry). Find the magnetic field here using an Amperian loop of radius s, closing your loop within the gap and adding up the enclosed displacement current. (c) Use charge conservation to determine the surface current density K(s) on each plate as a function of the distance s from the z axis. S
(d) Find the magnetic field halfway between the plates once again, this time by closing your I Amperian loop using a cylindrical surface that passes perpendicularly through one plate and is capped off through the charging wire. (The dis- K placement current through this surface is zero, whereas there are two separate contributions to lenc.) Verify that your answer matches part (b).
