Discussion Overview

The discussion revolves around the phenomenon of why an accelerated charge emits photons and loses energy, touching on concepts from classical electrodynamics and the Larmor formula. Participants seek explanations that do not rely heavily on mathematical formulations, as some are not yet familiar with the relevant theories.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant requests an explanation of why an accelerated charge emits photons and loses energy, expressing a desire for clarity without equations.
  • Another participant references the Larmor formula as a classical electrodynamics concept relevant to the discussion.
  • A participant expresses difficulty understanding the concept due to a lack of background in electrodynamics and requests a more accessible explanation.
  • Links to animations and images are provided to aid understanding of electromagnetic radiation from charges.
  • A participant acknowledges the usefulness of the provided resources but indicates a need for further study to grasp the mathematical aspects of the topic.
  • A follow-up question is posed regarding whether a moving charge is influenced by the field it creates.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the explanation of the phenomenon, as some seek simpler explanations while others reference more complex theories. The discussion remains unresolved regarding the specifics of the interaction between a moving charge and its created field.

Contextual Notes

Some participants express limitations in their understanding due to a lack of exposure to electrodynamics, which may affect their ability to engage with the topic fully. There are also unresolved questions about the influence of a charge's own field on its motion.

Who May Find This Useful

This discussion may be useful for students new to electrodynamics, individuals seeking conceptual clarity on electromagnetic radiation, and those interested in the foundational principles of physics related to charged particles and energy loss.

My days in high school are almost at an end and I don't want to run to my teachers with this question.
So can someone please explain this to me: why an accelerated charge emits photons and loses energy?
Links and references are also welcome. Thanks in advance.

This radiation is present in classical electrodynamics also. Google for "Larmor formula".

Ok...that went way over my head! I haven't learned electrodynamics yet! So could you kindly explain what is happening without equations?
 
thanx a lot! that gave me explanations to a lot of "untold stories". i admit that i need to pursue a little more of this to understand the full explanation with maths... but still, something, is much much better than nothing.
:D
 
one more question... will a moving charge be influenced by the field it creates?
