Talk:Spin magnetic moment

It is unsatisfactory to say that the spin magnetic moment is created because the particle has a property that has a name (spin), considering the spin article says that "the spin of a charged particle is associated with a magnetic dipole". That is, there´s a circular argument here. Isn´t the spin of a particle detected because it has a magnetic moment? How do you measure the spin of a particle? It seems that one of the concepts should be defined first and following sentences should be phrased accordingly.--190.190.87.136 (talk) 16:50, 30 July 2009 (UTC)
 * the spin article is wrong, since even particles with no magnetic moment can have spin, like the Z boson. 70.26.152.91 (talk) 04:09, 11 January 2010 (UTC)

Rewrote lead
There was no lead, but the very first section was rather inadequate. I hope it's clearer and correct now. M&and;Ŝc2ħεИτlk 16:44, 13 April 2013 (UTC)

Query section on maths of neutron moment
The section on maths says that the moment of the neutron is proportional to its charge, and is non-zero. These are contradictory. It seems there must. be a different formula for a neutron.

Perhaps there is confusion among g and gamma, but far from obvious. 2A04:4A43:4FCF:E8B8:313B:4CE6:7306:6B1B (talk) 13:26, 13 December 2022 (UTC)

Sign of the g-factor
It seems that there is confusion about the g-factor. The first equation with q=-e and g=-2 gives a positive magnetic moment which is not true for the electron. The text and the equations are in conflict because some use positive g-factor for the electron while others use a negative value. HappyDog271 (talk) 23:51, 9 February 2023 (UTC)

Merge into Spin (physics)
The history here is a lame echo spin history. The chemistry section is about spin. I think we should cut our losses and merge this with Spin (physics). Johnjbarton (talk) 03:47, 15 February 2024 (UTC)


 * Support. There are only a few incoming links, and most of them would actually be improved by linking to Spin (physics), or Electron magnetic moment or Nuclear magnetic moment instead. There are also the pages g-factor (physics) and Gyromagnetic ratio which are closely related to this, but take a wider approach by considering also the orbital angular momentum.
