I show that the observed large rotation-induced mutual friction in superfluid 3He close to Tc implies a reactive interaction between the normal fluid and a vortex, similar to a Magnus force. In the A phase the absence of a singular vortex core enables a purely hydrodynamic description of this interaction to be given, and I argue from hydrodynamics that the experimental observations require the existence of an intrinsic angular-momentum density of order (ρs/2m)1̂.
