That's about the size of it.  A constant B field does nothing to electrons
at rest.  Once they start moving, however its right hand rule.

I don't remember how exactly spin worked, but I'm pretty sure that photons
are multiples of 1/2 and electrons are integers.  I'm thinking of electron
spin in domains in a magnet, say.  I think it is the spin that is used to
model the B field interaction.  That's why a Magnetic monopole would be so
cool and odd.  An electron as a N and S pole and hence either a +1 or -1
spin... IIRC

Anyone remember their modern physics out there?
