The radially outward vectors represent the vector potential giving rise to this magnetic field in the region where x> 0. The vector potential points radially inward for x < 0.
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
Outside the capacitor, the magnetic field has the same form as that of a wire which carries current I. Maxwell invented the concept of displacement current to insure that eq. (1) would lead to such results.
• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor.
