  MHD equations are presented for the mixture of superfluid neutrons,
superconducting protons, and normal electrons believed to exist in the outer
cores of neutron stars. The dissipative effects of electron viscosity and
mutual friction due to electron-vortex scattering are also included. It is
shown that Alfven waves are replaced by cyclotron- vortex waves that have not
been previously derived from MHD theory. The cyclotron- vortex waves are
analogous to Alfven waves with the tension due to the magnetic energy density
replaced by the vortex energy density. The equations are then put into a
simplified form useful for studying the effects of the interior magnetic field
on the dynamics. Of particular interest is the crust-core coupling time which
can be inferred from pulsar glitch observations. The hypothesis that
cyclotron-vortex waves play a significant role in the core spin-up during a
glitch is used to place limits on the interior magnetic field. The results are
compared with those of other studies.
