Talk:London moment

Links with "The Left Hand Rule"[edit]

Can the London moment be linked in with the Left hand rule? (Yes) I assume that the magnetic field is generated as there is a moving charge within the superconductor induced by the superconductors motion - is that moving charge a by-product of the high conductivity of the superconductor, or is this an effect that can be detected/occurs under `normal' circumstances? (Yes).

Also. Does the effect require the use of a sphere? (NO)

I *think* that the resposnes to my questions (in brackets) are correct - but can anyone else out there provide some explanation or commentary?

See Barnett effect. This of course implies that the effect is not due to the actual motion of actual electrons. If so then it must be a purely quantum mechanical effect.just-emery (talk) 17:12, 3 June 2009 (UTC)[reply]

What if a ring is rotated instead of a sphere? If a ring produces a magnetic field then it cant be due simply to the orientation of individual electron spins either. just-emery (talk) 17:16, 3 June 2009 (UTC)[reply]

GPB Gyro Speed[edit]

The article says the gyros ran at 4000RPM but this paper http://iopscience.iop.org/article/10.1088/0264-9381/32/22/224001/meta;jsessionid=E0D57E8307F196B835F3388A3C6BC6D4.c4.iopscience.cld.iop.org says 80Hz (4800RPM).

So the two relevant references to the effect from 1982 and 1990 state that the original theory needed correction then that no theory was working (from the paper 8 years later). I know lots of quantum but this is an aspect of superconductivity I am not expert about. This article seems to need an expert to clarify this. Cechafin (talk) 23:47, 16 March 2017 (UTC)[reply]

This has nothing to do with quantum mechanics whatsoever — Preceding unsigned comment added by 2601:449:8200:A430:89D8:D926:81DB:E6EA (talk) 02:39, 9 July 2018 (UTC)[reply]
