Undergrad Does a Magnetic Monopole with Spin Create an Electric Dipole?

[DuckAmuck]

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.
