Electric field of an infinite carged wire in a conductive medium

Click For Summary
SUMMARY

The discussion focuses on the electric field generated by an infinite charged wire in a conductive medium. Participants seek references for understanding this problem, particularly when the conductivity (σ) of the medium is non-zero. While classical textbooks like Stratton, Panofsky-Phillips, Jackson, and Griffiths do not address this specific scenario, it is noted that Gauss's law remains applicable if the charge per unit length is known. A relevant reference is Section 6.9 of Franklin's "Classical Electromagnetism," although it does not cover the exact geometry in question.

PREREQUISITES
  • Understanding of Gauss's Law in electromagnetism
  • Familiarity with electric fields and charge distributions
  • Knowledge of conductive materials and their properties
  • Basic principles of classical electromagnetism
NEXT STEPS
  • Research the application of Gauss's Law in conductive media
  • Study Franklin's "Classical Electromagnetism" for insights on electric fields
  • Explore the effects of conductivity on electric fields in materials
  • Investigate advanced electromagnetism textbooks for specific geometries
USEFUL FOR

Students and professionals in physics, electrical engineering, and anyone studying electromagnetic theory, particularly those interested in the behavior of electric fields in conductive materials.

Hi,
I need to find a book where the problem of the subject is treated.
(I am assuming that charge is being fed to the wire by an external source,
so as to keep it constant)

Does anybody know a reference where this problem is treated?
I have looked for an answer in the classical textbooks (stratton,
panofsky-phillips, jackson, griffiths, etc,), and I've found nothing

Of course, if the conductivity of the medium is zero the answer is
well known, but if sigma is non zero, the answer seems to be not
that easy.

Many thanks

If the charge per unit length is known then Gauss's law still applies, so E is the same as with no conductivity. That type of problem is treated in Sec. 6.9 of Franklin, "Classical Eectromagnetism", but not for your specific geometry.
 
Hi Meir, many thanks for your answer, I think I've understood the point.
