Discussion Overview

The discussion centers on the possibility of the curl of the electric field (E) generated by a charged particle, particularly in the context of whether this occurs for static versus moving charges. The scope includes theoretical considerations of electromagnetic fields and their properties.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions whether there is a possibility of the curl of the electric field for a charged particle.
  • Another participant asserts that if the charge is moving and producing a changing magnetic field (B), there will be a curl of E.
  • A different participant clarifies that they are specifically discussing the electrostatic field of a static charge, implying that in this case, the curl of E would not exist.
  • It is reiterated that if the electric field is generated solely by stationary charges, then the rate of change of the magnetic field (dB/dt) is zero, suggesting no curl of E.
  • One participant references a previous statement indicating that a curl of E exists only if the particle is moving.

Areas of Agreement / Disagreement

Participants express differing views on the conditions under which the curl of the electric field exists, with some asserting it only occurs for moving charges while others emphasize the context of static charges. The discussion remains unresolved regarding the implications for static versus moving charges.

Contextual Notes

There are limitations regarding the assumptions about the nature of the electric field and the conditions under which the curl may or may not exist, particularly in distinguishing between static and dynamic scenarios.

like the divergence of a charged particle (whether + or -) Is there any possibility of presence of curl of elctric field of that particle?

If the charge is moving and producing a changing B field, there will be a curl of E.

i'm talking about the electrostatic field of a static charge!

if the electric field is composed of only stationary charges, then dB/dt=0
 
clem just said there's a curl of E only if the particle is moving
