Does anyone know if Nitrogen Dioxide gas is paramagnetic? The wiki states NO2 as paramagnetic, but I'm not sure if that is the liquid or gas.
That would be a nice control method for NO2 from reactions, to just have a magnet stuck to the inside of the flask.
Hmm, tomorrow morning I'll try generating some and find out.

Paramagnetism means that the species is weakly attracted to a magnetic field.
LOX will stick to the poles of a powerful horseshoe magnet, but liquid O3 is diamagnetic as is N2O4 a component of
liquid NO2.
The dimer is the low-temperature form of the dioxide.
Frozen NO2 is almost entirely made up of N2O4.

Exactly, so shouldn't that mean that if at slightly high temps, maybe ~30 C, that NO2 gas should stick to a magnet?

Yes, but the diamagnetic and paramagnetic phenomenon in solids/liquids/gases is always very weak. You won't notice much happening even if you put a
magnet next to your flask of NO2 gas.
