ri-science:Liquid oxygen is magneticLiquid oxygen sticks between the poles of a strong magnet until itboils away into its gas state. This is because it has unpaired electrons, which make each oxygen molecule a tiny magnetwith a dipole. Normally, when oxygen is in a flask or in the air, thesemicroscopic magnets point in all directions, cancelling out and meaning thatthere’s no net magnetic field. When it pours over the permanent magnet, the magneticmolecules all slightly align, creating an inducedmagnetic field, which reacts with the permanent magnet, making the oxygen stickto the poles. This is called paramagnetism. Click here to watch the video. -- source link
