3. Conservation of electric charge 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

4. Conservation of electric charge 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

5. Conservation of electric charge 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

6. Conservation of electric charge Vacuum displacement current is added by Maxwell to explain Ampere’s law Charges in vacuum
