The importance of large-scale magnetic fields in H I rotation curves of spiral galaxies is investigated. In contrast to other papers that try to render dark matter unnecessary, we assume that galaxies are embedded within a modified isothermal dark halo. The NGC 1560 magnetic field is derived from a simple prescription suggested recently by Sánchez-Salcedo for large luminous spirals. The detailed s...
