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 capacitor is a device used in electric and electronic circuits to store electrical energy as an electric potential difference (or an electric field) consists of two electrical conductors (called plates), typically plates, cylinder or sheets, separated by an insulating layer (a void or a dielectric material).A dielectric material is a material that does not allow current to flow and can ...
Imposing an electric field on a conductor gives rise to a current which in turn generates a magnetic field.

Thus, if the electric field at a point on the surface of a conductor is very strong, the air near that point will break down, and charges will leave the conductor, through the air, to find a location with lower electric potential energy (usually the ground). Electric breakdown is what we experience as a spark (or lightning, on a larger scale ...
The reason for the introduction of the ''displacement current'' was exactly to solve cases like that of a capacitor. A magnetic field cannot have discontinuities, unlike the electric field (there are electric charges, but there are not magnetic monopoles, at least as far as we know in the Universe in its current state). There cannot be a magnetic field outside the …
