I will try to put this very simply. As we know, a straight current carrying wire produces a magnetic field encircling the conducting wire. Also, as theoreticaly suggested, a displacement current is set up between the plates of the capacitor when there is a change in electric field (generally due to change in charge that appears on the plate).

17.1: The Capacitor and Ampère''s Law
The magnetic field points in the direction of a circle concentric with the wire. The magnetic circulation around the wire is thus (Gamma_{mathrm{B}}=2 Pi mathrm{rB}=mu_{0} mathrm{i}). Notice …
Magnetic field for parallel plate capacitor
A parallel plate capacitor produces a magnetic field when an electric current flows through it. This is because the movement of electric charges creates a magnetic field around the conductor, which can be …
capacitor
$begingroup$ Any movement of charged particles like ions, electrons etc in a magnetic field will generate some effect. At the ionic speeds involved, and low fields involved, and large other effects involved (chemical, electrical), the effect on the operation of the capacitor will so infinitesimally small as to be totally, completely, and ...
B8: Capacitors, Dielectrics, and Energy in Capacitors
The presence of the insulating material makes for a weaker electric field (for the same charge on the capacitor), meaning a smaller potential difference, meaning a bigger charge-to-voltage ratio, meaning a bigger capacitance. How much bigger depends on how much the insulator is polarized which depends on what kind of material the insulator ...

Passing a conductor through a magnetic field, or a magnetic field past a conductor, also generates a voltage in the conductor. This effect is used in generators and alternators. A transformer transforms voltages from one level to another level. It does this by converting electrical energy to magnetic energy, then converting the magnetic energy ...

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.
