  We present calculations of the magnetic moment and magnetic polarisability of
the neutron from the background field method. The calculations are performed on
$32^3\times64$ dynamical lattices generated by the PACS-CS collaboration and
made available via the ILDG. We consider uniform fields quantised by the
periodic spatial volume. We explore different approaches for improving the
quality of the fits used in the results. Also included are initial results for
the magnetic moment of the lowest lying negative parity nucleon states.
