Homework Help Overview

The discussion revolves around the conditions under which the magnetic field generated by moving charged particles, specifically electrons or protons, can counterbalance the electrostatic repulsion between them. The context involves concepts from electromagnetism and special relativity.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between velocity and the cancellation of electrostatic forces through magnetic fields. Questions arise regarding the relativistic implications of moving charged particles and their world-lines in different frames of reference.

Discussion Status

The discussion is ongoing, with participants questioning the foundational concepts of electromagnetism and relativity. Some guidance has been offered regarding the complexity of the topic, and there is an acknowledgment of the need for deeper exploration.

Contextual Notes

There is a suggestion that the topic may be more suited for an advanced physics forum, indicating potential gaps in foundational understanding among participants. The nature of the questions suggests a mix of classical and relativistic considerations that may not be fully resolved.

At what velocity...(sentence)

At what velocity do 2 parallel moving electrons (or protons) attractive magnetic field equal (and therefore cancel out) the electrostatic repulsion?

I'm not in school.

After further googling and pondering, I never realized how "relativistic" this line of thinking can be.

D'oh

I guess my next question then would be, "what would the world-line of one moving electron look like, in all frames of reference, at different velocities?" Would it draw the same path?

Naturally the third question would be, "Ok, classical electromagnetism states that accelerated charged particles induce acceleration in other charged particles nearby." How would relativistic-electrostatic mesh well here, being magnetisim doesn't exist and its all special relativity?

You might consider posting this in the advanced physics forum, not the introductory forum... (I have no idea what you're talking about in your last post :p )
 
Is it C?
