### Maxwell's Equations Gauss's Electric Field Law

1. The first term tells us to take the surface integral of the dot product between electric vector (E in V/m) and a unit vector (n) normal to the surface. The dot product gives the electrical field normal to the surface and the integral the total electric flux () passing through the surface. The second term is the net charge (qin Coulombs) enclosed within the surface (divided by a constant of proportionality 1/ε0). Together both these terms define the law in mathematical concepts. By knowing an electric flux distribution through a surface, we can find the charge contained by the surface. Conversely knowing the charge contained within a surface, the electric flux passing through the surface can be determined.

1. Maxwell's equations predict that static electric fields, i.e. field that do not change with time, are produced by charges. Charges are sources and sinks of field lines. Static electric field lines begin on positive and end on negative charges. Static electric field lines NEVER form loops. The static electric field is a conservative field. If you do work on a charge against the static electric field, this work is stored as potential energy. The potential energy is a function of position only. You can let the electric field do work to recover the energy you expended in moving the charge. In statics, Maxwell's equations for the electric field combine to give you Coulomb's law and the principle of superposition. Everything else is just vector addition. Maxwell's equations predict that static magnetic fields are produced by moving charges or currents. There are no magnetic charges, and therefore no sources and sinks for magnetic field lines. Static magnetic fields lines ALWAYS form close...
