  We consider mixed configurations consisting of a wormhole filled by a
strongly magnetized isotropic or anisotropic neutron fluid. The nontrivial
topology of the spacetime is allowed by the presence of exotic matter. By
comparing these configurations with ordinary magnetized neutron stars, we
clarify the question of how the presence of the nontrivial topology influences
the magnetic field distribution inside the fluid. In the case of an anisotropic
fluid, we find new solutions describing configurations, where the maximum of
the fluid density is shifted from the center. A linear stability analysis shows
that these mixed configurations are unstable.
