I was reading todays SMBC which asked what happens if you make a gas of magnetic particles

Comic strip

So what does happen if you make a gas of magnetic particles?

  • $\begingroup$ You mean ferromagnetic? I'm afraid it won't be gas, more like dust cloud maybe. $\endgroup$ – Mithoron Mar 12 '15 at 13:37
  • $\begingroup$ What do You understand by "magnetic"? $\endgroup$ – Georg Mar 12 '15 at 16:02

    $\begingroup$ Hmm, supposedly this question is unclear unless you provide the background you have of what "magnetic" is. Even so, it would be more appropriate at physics.SE. $\endgroup$ – M.A.R. Mar 12 '15 at 17:31

    $\begingroup$ If so please migrate, since the comic doesn't define magnetism I don't know what to say, in the same way asking what happens when you pour water on paper seems self contained and obvious until someone asks what material is the container made out of. Of course the answer may be that a magnetic gas isn't possible $\endgroup$ – Tom J Nowell Mar 12 '15 at 17:34

    $\begingroup$ Oxygen is a gas and it is paramagnetic, so is nitrogenoxide and nitrogendioxide. When talking about forromagnetic properties, that should strictly speaking not possible. Aerosols, like @Mithoron suggested might be the best you can do. However, I think it fits our site, but you might get more attention at physics.se. Let it play out for a while and flag for migration, if you want to try it there. $\endgroup$ – Martin - マーチン Mar 12 '15 at 18:57

If you heat up the magnet above Curie temperature (or more drastically just evaporates it), the magnetic spins will be randomly aligned and the magnetic field is not produced anymore (at higher temperature).

  • $\begingroup$ Hmmm this looks like one of those questions where we could come to a different answer if we considered a gas of marbles. (We note the ideal gas law works for marbles in cylinders over a vibrator.) $\endgroup$ – Joshua Jul 16 '15 at 4:29
