Capacitor Stores Energy In The Form Of A Magnetic Field

Both magnetic fields store some energy.

Capacitor stores energy in the form of a magnetic field.

In the limit of a fully charged capacitor there is no displacement current maintaining a magnetic field and all the energy is stored in the electric field. A charged capacitor contains the same number of electrons as an uncharged capacitor. The energy put into the magnetic field during charging is lost in the sense that it cannot be feed back to the circuit by the capacitor. If you move the electrons around you change the amount of stored energy you don t change the capacitance.

The purpose of a capacitor is not to store electrons but to store energy. Capacitance is the ability of a component or circuit to store energy in the form of an electrical charge. But electromagnet creates its variable magnetic fields based on how much current it carries. Begingroup there s a magnetic field associated with a changing electric field in tem propagation of an em wave through space which is how it propogates the changing e field begets the m field the changeing m field begets the e field leapfrogging each other so i don t see why that should not apply between capacitor plates.

Magnetic field can be of permanent magnet or electro magnet. The dimension of this electro magnet is responsible to create the strength the magnetic field and hence the energy stored in this electromagnet. A capacitor stores energy in the form of a electric field specifically electro static charge an inductor stores energy in the form of a magnetic field. T in a capacitve circuit with dc voltage applied current flows when capacitve voltage equals the source voltage.

As the capacitor charges the magnetic field does not remain static. A capacitor stores energy in the form of a electric field specifically electro static charge an inductor stores energy in the form of a magnetic field. Electrons don t easily disappear or appear they have to be moved somewhere. This results in electromagnetic waves which radiate energy away.

When a capacitor is connected to a power source it accumulates energy which can be released when the capacitor is disconnected from the charging source and in this respect they are similar to batteries.
