Re: solenoids

Has anyone come across manufactured left-hand wired solenoids?
McMasters and a few other machinist parts catalogs only list
right-hand wired solenoids.

We are looking for them (and would rather not make them) for use in
the physics lab because a number of students in our intro physics
classes come to the conclusion that the current enters a solenoid on
the end with the south pole and leaves on the end with a north pole.
I suspect that this is due to the chirality of the solenoid. Has
anyone else seen this observation on the part of the students?

Thank you,

If you could overcome the aversion, a heavy nail and a foot or two
of copper wire, perhaps a limiting resistor and a compass would be
a useful 'guided discovery'.
