Angular momentum in electric field and magnetic field

Click For Summary

Discussion Overview

The discussion revolves around the conservation of angular momentum in the context of electric and magnetic fields. Participants explore the availability of references and articles on this topic, particularly in relation to research and academic inquiries.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant expresses a lack of references on the conservation of angular momentum in electric and magnetic fields, seeking assistance for their PhD research.
  • Another participant suggests that the inquiry may relate to energy density, Poynting vector, and stress-energy tensor relationships.
  • A different participant asserts that angular momentum is not generally conserved in an electric field, introducing a point of contention.
  • Some participants note that there are indeed many articles on the subject, indicating a broader scope than initially perceived by the original poster.
  • One participant mentions working on a paper related to this topic and considers a problem from Jackson as a potential starting point.
  • Another participant acknowledges a suggestion but indicates they have already submitted an abstract to their professor, despite finding the suggestion interesting.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the conservation of angular momentum in electric fields, with some asserting it is not conserved while others suggest there are ample resources available on the topic.

Contextual Notes

The discussion reflects varying interpretations of angular momentum conservation in electric fields, with some participants referencing specific problems and literature while others express uncertainty about the availability of resources.

I am just wondering why there are no references and articles talking about the conservation of angular momentum in electric field and/or magnetic field! does anybody has any thing to help me because am a phd student and looking for that subject for my research.
thank all

What have you been looking for? It kind of sounds like you are asking about the energy density, Poynting vector, and stress energy tensor relationships.

Erm... angular momentum is not generally conserved in an electric field.

There are plenty of articles...
As Peeter implied, its is quite a broad subject.

It appears from your other posts you are doing a Jackson problem to 'prove AM conservation in Electric field'.

actully i am working on prepaper about that subject and i found maybe jakson problem will be a good start point for me..
regards
 
thank you so much for your pleasent suggestion,,but unfortunately I've already written the abstract to my proffesor! but your experiment indeed interesting.
thank you
