Indeed Horace you must be right that each winding layer not
compensated by a reverse wound layer must act as a single turn
current loop around the major axis, with the same current as in the
winding. This effect, resulting from a turn of wire not being flat
in reality, had never occurred to me, many thanks for the
enlightening post!

Thanks Michel. You might might also find it of interest then that
the implications of my little experiments along these lines go well
beyond this though, by suggesting that the interpretations of a
variety of Aharonov-Bohm experiments may be invalid. These A-B
experiments examine the interference effects upon electrons,
neutrons, or photons by thin contained magnetic fields, such as a
field contained by a magnetized Iron whisker, or a circularly
polarized laser directed through an optical fiber. The
interpretation of these experiments is typically that the B field is
fully contained, and thus the "action" of the B-field contained
equivalent to a slit pair is due solely to the A field which extends
out externally to the contained B field. I think the fact is the
affected particles, moving particles, have B fields which enter the
domains of the enclosed B fields, and thus directly interact,
superimpose, momentarily changing the energy of the enclosed B
fields, resulting in displacement of the motional particles and
resulting in an interference pattern.
