NO2 Paramagnitivity
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.
