| Abstract: | When the circular parallel-plate capacitor is connected to an alternating current,the magnetic field will appear both inside and outside the plates with the electromagnetic wave radiating. The radiated electromagnetic energy is equal to the reserved energy which the capacitor lost. |

| Keywords: | circular parallel-plate capacitor magnetic field strength displacement current conduction current energy flow density Poynting's vector |
