Abstract
Vortices in spin- superfluids generically carry magnetic fields inside their cores, so that even neutral superfluid vortices may be thought of as magnetic flux tubes. We give a systematic analysis of this `vortex magnetic effect' using effective field theory, clarifying earlier literature on the subject. Our analysis shows that in superfluid Helium- the vortex magnetic effect may be large enough to be experimentally detectable.
