Your microwave generates a strong magnetic field

The only thing in the microwave that would generate a strong AC
magnetic field would be the HV transformer

Not so; you're forgetting the AC power line itself, which
obviously is carrying a fairly high current wheneve the
microwave is operating.

That's true, and I hadn't thought of that, but the amount of magnetic
field it would create really just depends on the amount of area inside
the current loop. Assuming that this is wired in the usual way, that
loop is pretty small, since the two conductors are parallel to each
other and maybe just 1/4" apart.

I don't think that would do it, but if there was some sort of wierd
(and possibly illegal) wiring scheme that created a current loop that
surrounded the room, then that would certainly cause such a problem.
