  Neutron stars might have multipole magnetic fields as implied by recent
observations of pulsars. The presence of the quadrupole field might have an
effect on the interaction between the disc and the neutron star depending on
the location of the inner radius of the disc and the strength of the quadrupole
field. For a quadrudipole stellar field, we calculate the toroidal field
generated within the disc, the magnetospheric radius and the torque exerted
onto the star. Also, we deduce the effect of the rotation of the star on the
magnetospheric radius which is relevant even for pure dipole magnetic fields.
