I wish I could answer that question, but I cannot.  Instead, I'm holding
one
possible believe that the field as we think of it is not a complete
description
of how a magnet affects other magnets or materials.

Through a series of constructions I can move from the notion of a disk
that is
rotating in a magnetic field that has magnets rotating with the disk, to a
large scale construction that has to consider non-relative movement
through
space.  Specifically, magnet and wire move together through space and this
is
going to induce a potential in the wire as a function of that movement,
even
where that movement is the rotation of the residing planet, ot orbit
around
its star, the star system moving around its galaxy, and that galaxy moving
through the universe.  Do you think any of those movements can be used to
induce the potential in the wire that is in an attached magnetic field?

Those constructions are long and complex.  It would take a lot of posting
and
reading and understanding to see it.
