The theory of "magneto-hydrodynamics" got written up in Scientific American about 6 months ago. The reason I suggest it is that the equations of motion for such a fluid are the Bernoulli equations with additional terms for the magnetic interaction. If convection produces a two-dimensional system, it might be possible to cook up a three-dimensional one by making the fluid magnetic and adding a magnetic field. (Sounds like it would be somewhat arti- ficial; but I think that may be because all of our "non-artificial" examples are physical systems which we can solve - and we produce them by simplification of real systems.) -- Jerry decvax!yale-comix!leichter
