Conservation of electriccharge
Free charge
a free charge is simply a charge free to
accelerate under the influence of a force.
For example, a lone proton is a free charge.
If another lone proton were to interact
with this proton, then they both would
accelerate away from each other. This
behavior is common in conductors, as
electrons aren't bound by their parent
atoms
Conservation of electriccharge
an insulator harbors bound charges. These
charges can't move on a large,
macroscopic scale, but can move within
their atoms. This is how polarization can
occur; an outside electric field can exert a
force on bound electrons, which all move
to one side of their respective atom,
resulting in the said insulator having
opposite sides of opposite charge.
Bound charge
Conservation of electriccharge
When a body is magnetized,
there will be a vector potential in
the surrounding region which
gives rise to a current density Je
called magnetization current
density.
Charge involving
in
magnetization
currents
Conservation of electriccharge
Vacuum displacement current is
added by Maxwell to explain
Ampere’s law
Charges in
vacuum
