What happens in a gas of magnets? This SMBC comic asks what happens if you make a gas of magnetic particles:

I was wondering whether anyone has run into actual examples of this or something like it. A classical example similar to this would be a gas comprised of electrically charged particles (possibly in a magnetic field), if the temperature is high then this is essentially plasma physics (which, if memory serves, by it's nature does not include dipole - dipole interactions).
So, are there practical practical, real life situations that can be modelled by a gas of point like dipoles? How do these systems behave?
My own thoughts on this would be


*

*This gas would effectively behave like a ferromagnet and you would get domains of similarly oriented dipoles.

*The dipole - dipole interaction within those domains is attractive and the domains would collapse forming a larger single dipole.

*In effect this would look very much like the gravitational evolution of a neutral gas except that "gravity" would obey the inverse cube law of dipole - dipole interaction.

 A: Dipole gas.
If the dipoles are weak, there are probably many atoms with non-zero dipole moment that can be gas or plasma.
If your dipoles are strong, their strength exceeding normal molecular bonds, I would say that the situation would lead to a condensation of the gas to liquid or solid phase. And you could probably break the bonds (and keep it gaseous) by heating to sufficient temperature $kT \sim E_{bond}$. In that case, there would be no major orientation, I dare to say. 
Consider it as hypothetical, many things could have escaped me.
The nice reference of @RedGrittyBrick speaks about $\sim$zero temperature, no Brown motion, no molecule(dipole) collisions.
A: This morning I was thinking about this idea.
One idea is to modify a Particle -In-Cell simulation of plasma so the particles are little circular rings if charge and Mass that could rotste on their axes . Their translation would be pushed around by Lorenz force but their angular momentum/ magnetic dipole moments would be driven by torque due to magnetic field.
