Homework Help Overview

The discussion revolves around providing a qualitative description of Maxwell's equations in non-polarizable, non-magnetizable media. Participants are exploring how to articulate these fundamental equations without delving into mathematical details.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the qualitative aspects of Gauss's Law, the absence of magnetic monopoles, Faraday's Law, and the Ampere-Maxwell Law. Questions arise regarding the sufficiency of these descriptions and whether a more physical interpretation is necessary.

Discussion Status

Some participants have provided feedback on the adequacy of the qualitative descriptions, suggesting corrections and affirming that the explanations are generally acceptable. There is an ongoing exploration of how to enhance the clarity and physical relevance of the explanations.

Contextual Notes

Participants express concern about losing marks on similar questions in tests and exams, indicating a desire for clarity and completeness in their qualitative descriptions.

Homework Statement


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

Homework Equations


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


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
 
Physics news on Phys.org
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.
