Discussion Overview

The discussion revolves around the concept of messenger photons in electromagnetism, specifically focusing on the distinction between "repulsion force carriers" and "attraction force carriers." Participants explore the nature of interactions between charges and the theoretical implications of these terms.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions the difference between repulsion and attraction force carriers in electromagnetism, suggesting that these two types of messenger photons should be distinguished.
  • Another participant expresses confusion over the terms and states that they have not encountered this distinction before, indicating that there may not be a recognized difference.
  • A later reply clarifies that charges do not "know" about each other but respond to the electric field, suggesting that the interaction is independent of the charge type.
  • There is a mention that "messenger" photons, often referred to as "virtual" photons, are mathematical constructs used in quantum field theory rather than literal carriers of force.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the distinction between repulsion and attraction force carriers. There are competing views regarding the existence and nature of these terms, with some participants questioning their validity.

Contextual Notes

The discussion highlights a lack of clarity regarding the definitions of force carriers in electromagnetism and the role of virtual photons in theoretical frameworks. There are unresolved assumptions about the nature of charge interactions and the implications of these concepts.

What's the difference between "repulsion force carrier and
attraction force Carrier" in electromagnetism interactions?
We know that these two messenger photons should be
distinguished. But in what features and details?

I've never heard of these terms. :confused:

So far as I know there's no distinction.

Can you provide a quote and a link to where you saw this? :smile:
 
my apologize,i have ever seen that anywhere to provide a quote. but i meant how two specific charges know when interact by attraction force or repulsion force?
 
(One charge doesn't "know" that the other charge is there, it only "knows" that it is in an electric field, but anyway …)

The field works the same way whether the charge is positive or negative.

"Messenger" photons (and electrons), usually called "virtual" photons (and electrons), are only a mathematical idea that helps to describe the approximations in perturbation theory in quantum field theory.

They don't literally "carry" the force. :smile:
