Well, if you could surround the planet with a powerful changing magnetic
field, I believe you could heat the core using hysteresis. But I don't know
how that would work. I suppose you might wrap several loops of wire around
the planet and then run a (very very big) alternating current through it to
create the magnetic field. Then sit back and let the H field do it's thing
in the core.
Single magnetic poles don't seem exist in nature (else, you could orbit a
super-strong north pole around the planet and a corresponding south pole on
the opposite side). While they don't seem to exist, I'm pretty sure it has
not been proven that they *can't* exist, so if you wanted to make some ship
that generates one end of a magnetic pole, I think the pseudo-science would
be true enough... So, ya gonna build us a pair of Magneto-polar generator
ships? ;)
