Resum
Many aspects of NS physics are sensitive to the internal structure of
their magnetic fields, although we have no direct probe of these.
Instead we rely on theoretical models, where the star is usually
assumed to have a barotropic equation of state: pressure is a function
of density alone. Many magnetic equilibria have been constructed in
this way, and whilst some are known to be *unstable*, none have been
proved stable - and hence good physical models. We discuss testing the
stability of these candidate equilibria, in the search for an
astrophysically relevant model of a NS's magnetic field.
