Since the capacitor plates are charging, the electric field between the two plates will be increasing and thus create a curly magnetic field. We will think about two cases: one that looks at the magnetic field inside the capacitor and one that looks at the magnetic field outside the capacitor.
The y axis is into the page in the left panel while the x axis is out of the page in the right panel. We now show that a capacitor that is charging or discharging has a magnetic field between the plates. Figure 17.1.2: shows a parallel plate capacitor with a current i flowing into the left plate and out of the right plate.
Because the current is increasing the charge on the capacitor's plates, the electric field between the plates is increasing, and the rate of change of electric field gives the correct value for the field B found above. d dt
An electric field is created between the plates of the capacitor as charge builds on each plate. Therefore, the net field created by the capacitor will be partially decreased, as will the potential difference across it, by the dielectric.
That post improved quite significantly! The electrons don't actually pass through the capacitor. As one plate of a capacitor gains electrons, that creates an electric field that repels the electrons of the other plate, and it's those electrons that go on to move through the stuff on the other side of the capacitor.
