14.4: Energy in a Magnetic Field
The magnetic field both inside and outside the coaxial cable is determined by Ampère''s law. Based on this magnetic field, we can use Equation ref{14.22} to calculate the energy density of the magnetic field. The magnetic energy is calculated by an integral of the magnetic energy density times the differential volume over the cylindrical shell.

8.9: Displacement Current and Ampere''s Law
Note that at no point is current flowing directly from one side of the capacitor to the other; instead, all current must flow through the circuit in order to arrive at the other plate. Even though there is no current between the plates, there is current in the wire, and therefore there is also a magnetic field associated with that current.

Electric Fields and Capacitance | Capacitors | Electronics Textbook
Fields have two measures: a field force and a field flux. The field force is the amount of "push" that a field exerts over a certain distance. The field flux is the total quantity, or effect, of the field through space. Field force and flux are roughly analogous to voltage ("push") and current (flow) through a conductor, respectively ...
