Is there a good reason why this should be a separate article from proton?TR 08:44, 22 May 2014 (UTC)
Value[edit]
Can we put the value of the proton magnetic moment in? It is on the proton page, but not this one.— Preceding unsigned comment added by 152.3.175.177 (talk • contribs) 14:53, 25 November 2014 (UTC)
Measurement method[edit]
Info re the measurement method of this magnetic moment is missing from the article.--193.231.19.53 (talk) 11:00, 12 January 2015 (UTC)
Comparison to electron magnetic moment measurement[edit]
Can this quantity be measured similarly to the case of electron by a one-proton/(particle) quantum cyclotron?--5.2.200.163 (talk) 16:03, 1 August 2018 (UTC)
Calculation of the magnetic moments of protons, neutrons, and other baryons[edit]
The text states "straightforward calculation gives fairly accurate estimates for the magnetic moments of protons, neutrons, and other baryons" with reference to Perkins "Introduction to High Energy Physics". This statement appears is incorrect. Perkins, Ch. 5.2, p. 194, states "we are unable to calculate the value of g-2 [for proton and neutron]" except for their ratio of -3/2. I am looking forward to a correction by the author.[1] [2] Aoosten (talk) 09:56, 16 November 2018 (UTC)
- The computation of magnetic moments in the way described is a curious thing - on the one hand as it is done this way it is quite simplistic - ordinary quantum mechanics, non-relativistic, gross simplification of quark masses, while on the other hand it works very well - for most any baryon actually! As for the Perkins reference - the citation you give is dated to 1972...try a more uptodate version. See also the article on neutron magnetic moment. (and "E+m" must refer to units in which c=1; commonly used, I believe) Bdushaw (talk) 06:47, 17 November 2018 (UTC)

Merge "proton magnetic moment" and "neutron magnetic moment" articles?[edit]
I contributed most to the neutron magnetic moment article, but have been perpetually bothered by the fact that this article is quite redundant with the "neutron magnetic moment" article. I am unsure, but perhaps creating a new article "nucleon magnetic moments" which would be composed of the neutron and proton articles merged. The neutron and proton magnetic moment articles would then be redirected to this more general article. Thoughts anyone? Bdushaw (talk) 07:23, 23 September 2022 (UTC)
- The two articles do have much in common so they could be merged. However one important difference is that the proton magnetic moment is much more useful in chemistry, since proton NMR is a very widely used method for determining molecular structures. Perhaps this is why the Neutron magnetic moment article has not been edited since 2015.
- So for a merged article I would suggest the following order of presentation: 1) first the features which are common to both proton and neutron magnetic moments. 2) the specific features of proton moments, including a short section mentioning Proton NMR and its use in structure determination, with a heading See also Proton nuclear magnetic resonance. 3) the specific features of neutron moments, including uses for determining the properties of neutrons.
