Popis:	Vortices in spin-$0$ 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-$4$ the vortex magnetic effect may be large enough to be experimentally detectable. Comment: v2: corrected an error which does not change the conclusion, improved exposition
