Qualitative description of maxwells equations

[stunner5000pt]

Homework Statement

Give a qualitative description of maxwell's equation s in non polarizable, non magnetizable media.

Homework Equations

\oint_{S} E \cdot dA = 4\pi\int_{V}\rho d\tau
\oint_{S} B \cdot dA = 0
\oint_{P} E \cdot dl = -\frac{1}{c} \frac{d}{dt} \int_{S} B \cdot dA
\oint_{P} B\cdot dl = \frac{4\pi}{c} \int_{S} J\cdot dA +\frac{1}{c} \frac{d}{dt} \int_{S} E \cdot dA

The Attempt at a Solution

Gauss Law : The total electric flux over a closed Gaussian surface S is given by 4 pi Q enc where Q enc is the charge enclosed by surface S in volume V.

No magnetic monopoles:The total magnetic flux over a closed surface S is zero. This means that the net magnitude of the vector components of the magnetic field that point inward must equal to the net magnitude of the vector components that point outward.

Faraday's Law: The path integral of the electric field along the boundary P over a closed surface S is given by -1/c times the time derivative of the magnetic flux over the surface S.

Ampere-Maxwell Law: The path integral of the magnetic field along the boundary P over a closed surface S is given by sum of hte total current over the surface of S and the time derivative of the electric flux over the surface S.

I ALWAYS lose marks on questions like this on tests and exams. Are these descriptions are sufficient? Do they need more detail??

Thanks for your help

The line integrals for E and B are closed paths around an OPEN surface.

are these sufficient as qualitative explanations for maxwell equations??

I explained the math behind it but should i explain what it means in more physical terms?

TYhey are OK, with the correction.
