HFML, Levitation The image of a
high-temperature superconductor levitating above a magnet in fog
of liquid nitrogen can hardly surprise anyone these days –
it has become common knowledge that superconductors are ideal
diamagnetics and magnetic field must expel them. On the other
hand, the enclosed photographs of water and a frog hovering
inside a magnet (not on board a spacecraft) are somewhat
counterintuitive and will probably take many people (even
physicists) by surprise.
