AI Customer ServiceYou are correct, that while charging a capacitor there will be a magnetic field present due to the change in the electric field. And of course B contains energy as pointed out. However: As the capacitor charges, the magnetic field does not remain static. This results in electromagnetic waves which radiate energy away.
The energy U C U C stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up.
However: As the capacitor charges, the magnetic field does not remain static. This results in electromagnetic waves which radiate energy away. 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.
Every magnetic field contains some form of energy, which we generally refer to as Magnetic Energy, W m. With the energy stored in a magnetic field being one of the fundamental principles of physics, finding applications in various branches of science and technology, including electromagnetism and electronics.
The energy UC stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up.
The magnetic field that occurs when the charge on the capacitor is increasing with time is shown at right as vectors tangent to circles. 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.
