untruncated version of question: As electrons move through a wire, is the direction of the curl of the magnetic field lines observed derivable from an underlying property?
===========================
more detail (only to further clarify my question as useful):
> looking for a mechanistic understanding, if possible, much like 'temperature' is derivable from the mean kinetic velocity of the molecules of the medium
> another way to ask the question, would be that if you point your thumb in the direction of the current, and use the right-handed-rule, why are the magnetic field lines curling toward you, instead of away from you? (and it's not a question about sign convention, in that, if you flip the sign convention, and point your thumb the opposite way, in the direction of the electron travel, and use a left-handed-rule, same question about why the field lines are curling as they are, instead of the other way? )
> one friend of mine speculated it might derivable somehow, from the 'spin' of electrons...?
