Why magnet can attract liquid oxygen but not aluminium?both paramagnet

lundi 29 juillet 2013

A magnet only attract ferromagnetic material because they have magnetic domains which will align to form magnetic dipole when external magnetic field applied.

Paramagnet dont have domains. Due to the presence of some unpaired electron, they will cause the realignment of the electron path when external magnetic field applied.

So they should be attracted by magnet also, eg liquid oxygen.

But why not aluminium ? is that because of the temperature or the mass of the paramagnetic material?

Thank you
