An electric charge feels its own self electric field

AI Thread Summary
An electric charge generates an electric field that influences other charges, but traditionally, it is believed that a charge does not feel its own field. However, recent discussions suggest that a charge does indeed feel its own electric field, raising questions about why this effect is often ignored in classical electromagnetism. The Abraham-Lorentz force is mentioned as a relevant concept that may explain this phenomenon. For further understanding, the Feynman Lectures on Physics, specifically Volume 2, Chapter 28, provides valuable insights. This topic highlights the complexities of electromagnetic interactions and the need for deeper exploration.

Hello,

In classical electromagnetism, we learn that an electric charge generates and electric field which other charges can feel through a force. But the source charge does not feel its own generated electric field.

In reality, a charge feels its own field. Why are we able to ignore this effect? Is it truly small for all practical purposes?

Thank you!

How do you know this?
 
Well, I was reading something about the Abraham-Lorentz force. But I need to read more before I can share more explanations...
 
The Feynman Lectures on Physics, Volume 2, Chapter 28, has an excellent introduction to this question. , which is very readable, although perhaps somewhat dated. It is available for free online here.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
