Electric Dipole Moment of a Magnetic MonoPole ? |
On the topic of magnetic monopoles, Fanz Heymann
once said:
"If a putative [magnetic] monopole is, by symmetry
with the electron, a fermion, it will have spin and a
concomitant *electric* dipole moment, ..."
Dirac calculated that the elementary magnetic
mono-pole charge is given by (in CGS)
g = hbar*c / 2*e = e / 2*fsc ~ (137 / 2) e
where "fsc" is the fine structure constant.
Given the mass and charge of an electron, QED is
capable of predicting the magnetic dipole moment
of the electron in terms of e, m, c, and hbar.
It should be possible to predict the spin and (zeroeth
order) electric dipole moment of an elementary magnetic
monopole in a similar or complementary manner. Old
Man wonders what the zeroeth order result might be.

The "Bohr *electron*" would be the Bohr magneton with g replacing e,
and the electron mass by the monopole mass
The Lande factor and the spin of the electron and the monopole would
be identical
So the electric dipole moment, to zero order, of the monopole would be
ghbar/(2m'c) (Gaussian units)
Where the m' is the monopole mass.

Yes ! Old Man attempted the same, but wasn't confident
of the transformation in dimensions between the magnetic
dipole moment, current*area, and the electric dipole
moment, distance*charge, such that
[magnetic dipole] => [electric dipole] * [speed = c]
Thanks

Wouldn't you have to know the mass of the monopole?

There is no MONO POLE..evry pole can be viewed from 2 ends.
