What I am looking for is any portion of the wire that would have a field and
motion that would induce a potential in the opposite direction around the loop.
I don't see any.

this construction should induce a current around the loop in a specific
direction.

The induced current depends on the flux through the loop, and
any cyclic (repeating) movement of magnets will return to the same
flux condition once per cycle... thus, the time derivative of the
flux averages to zero; this means the loop induction is an AC current,
not a 'specific direction' i.e. a DC current.

That 'time derivative of the flux' is proportional to the induced
voltage
on the coil, of course. It is normal procedure to use a diode,
or a switch, to make the alternating induced voltage produce a DC
current, if that's wanted. Even using magnetic materials that
switch character, the flux cannot rise to infinity, it MUST induce
AC in the coil (high magnetic fields would mechanically destroy
the materials of your apparatus if you had some scheme that
really DID drive flux ever-higher).
