  Condensed matter systems can host emergent `vacua' with particles, fields and
dimension different from that of the universe we inhabit. Motivated by the
appearance of emergent gauge fields with both electric and magnetic charges, we
consider the fate of electromagnetism in two dimensions in such a setting. We
find that generically electromagnetic fields are damped due to resistive
effects. However, we can still identify a magnetohydrodynamic regime. It
exhibits magnetosonic waves which, unlike in $d=3$, are isotropic, to which
there is a contribution from the odd viscosity coefficient present in the
system. Further, we find a dynamo action, which unlike in $d=3$ requires
compressibility of the flow.
