Well, the primary cause for this effect is high magnetism scientists with wayyy too much free time. The secondary cause is magnetisation of just enough blood cells.
Stick anything in a magnetic field and diamagnetism (which is the opposite polarity from ferromagnetism) generates a repulsive force. If your magnetic field is big enough (and pointing upward), you can levitate the object.
I'm pretty sure that's how it works, anyway. IIRC, liquid oxygen has a higher diamagnetic, um, thingy (moment?) than most stuff, so you can make a blob of LOX float in between big-but-not-ludicrous magnets pretty easily.
