Static electromagnetic field capacitor

Capacitors: why is the energy not stored in a magnetic field?

When a capacitor is charging, the rate of change $dE/dt$ of the electric field between the plates is non-zero, and from the Maxwell-Ampère equation this causes a circulating magnetic field.

Understanding the electromagnetics of real capacitors

This story or context for how the fields interact inside the capacitor allows us also to understand why there are no "ideal" capacitors in real life. Here is what it tells us: The

Electric Fields and Capacitance | Capacitors | Electronics Textbook

The ability of a capacitor to store energy in the form of an electric field (and consequently to oppose changes in voltage) is called capacitance. It is measured in the unit of the Farad (F).
