Angular momentum in electric field and magnetic field

Click For Summary
SUMMARY

The discussion centers on the conservation of angular momentum in electric and magnetic fields, highlighting a lack of references and articles on the topic. A PhD student seeks guidance for research, specifically mentioning the Jackson problem as a potential starting point. Participants clarify that angular momentum is not generally conserved in electric fields, indicating the complexity of the subject. The conversation emphasizes the need for further exploration of related concepts such as energy density, Poynting vector, and stress-energy tensor relationships.

PREREQUISITES
  • Understanding of angular momentum conservation principles
  • Familiarity with electromagnetic theory, particularly electric and magnetic fields
  • Knowledge of the Poynting vector and its implications in electromagnetism
  • Experience with the stress-energy tensor in the context of field theory
NEXT STEPS
  • Research the Jackson problem related to angular momentum conservation in electric fields
  • Explore the relationship between energy density and angular momentum in electromagnetic fields
  • Study the Poynting vector and its role in energy transfer in electric and magnetic fields
  • Investigate the stress-energy tensor and its applications in field theory
USEFUL FOR

PhD students, researchers in theoretical physics, and anyone studying the conservation laws in electromagnetism.

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
