The applet represents and oscillating electric dipole.
The positive and negative charges on the capacitor plates constitute an electric dipole. If after charging the capacitor plates are short circuited through an inductor L, it behaves as an oscillator (tank circuit). The capacitor is discharged through inductor. During this discharge the current through the inductor increases and becomes maximum when the charge on the capacitor is zero. Due to this current, the capacitor is charged in opposite direction till the current in inductor becomes zero and the process is repeated continuously.
As the charge on the capacitor changes, the electric field between the plates changes. A changing electric field generates a magnetic field and a changing magnetic field generates an electric field. The two fields, which produced due to change in each other, are perpendicular to each other.
Thus if the blue lines represent electric field lines, the red lines represents magnetic field. There is an oscillatory current between the two plates through the inductor.
Due to these changes the field are not remains stationary but they are moving i.e. there properties changes at a point in space and creates electromagnetic waves whose direction of motion is perpendicular to electric and magnetic fields both.© BrainMass Inc. brainmass.com October 3, 2022, 11:39 pm ad1c9bdddf>
