liquid oxygen

Strangely, liquid oxygen (LOX) is pale blue in colour and is paramagnetic.

Paramagnetic materials are attracted to magnetic fields (like the poles of a magnet) but unlike ferromagnets they do not retain any magnetization in the absence of an externally applied magnetic field (so don't expect liquid oxygen to attract a piece of steel).
