Discussion Overview

The discussion revolves around the theoretical implications of a magnetic monopole possessing non-zero spin and whether this would result in an electric dipole moment. The scope includes theoretical exploration and conceptual clarification regarding magnetic monopoles and their properties.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants propose that a magnetic monopole with non-zero spin could lead to a non-vanishing electric dipole moment, drawing a parallel to how an electric charge with spin results in a magnetic dipole.
  • Others question whether the relationship between spin and dipole moments is straightforward, suggesting that the situation may be more complex than it appears.
  • Some participants note that magnetic monopoles are not part of the Standard Model and have not been observed, raising questions about their existence and implications.
  • There are mentions of theoretical proofs suggesting that there should be either one magnetic monopole in the entire universe or none at all, indicating a potential limitation in the existence of such entities.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between spin and dipole moments in magnetic monopoles, and there is no consensus on the existence or implications of magnetic monopoles within the framework of current physics.

Contextual Notes

Limitations include the speculative nature of magnetic monopoles, their absence in the Standard Model, and the unresolved status of their existence in the universe.

TL;DR
Results in electric dipole?
If you have a magnetic monopole with non-zero spin, would this result in an electric dipole? Just like an electric charge with spin results in a magnetic dipole?

You seem to think that the spin causes the dipole, perhaps it's more involved than just considering the spin?

Yes, a spinning monopole is expected to have a non-vanishing electric dipole moment. For example, see: Electric Dipole Moment of Magnetic Monopole, where the introduction states:

As background, of course, magnetic monopoles don't exist in the Standard Model and have never been observed. It is a logical possibility that Nature doesn't seem to have been interested in trying out.

But are there more rigorous explanations about why they should not exist ?

IIRC there are proof that there should be either one magnetic monopole in the entire universe or none at all. General background at https://en.wikipedia.org/wiki/Magnetic_monopole
 
Thank you for the answer.
