  We present a combined theoretical and experimental study, investigating the
origin of the enhanced non-adiabaticity of magnetic vortex cores. Scanning
transmission X-ray microscopy is used to image the vortex core gyration
dynamically to measure the non-adiabaticity with high precision, including a
high confidence upper bound. Using both numerical computations and analytical
derivations, we show that the large non-adiabaticity parameter observed
experimentally can be explained by the presence of local spin currents arising
from a texture-induced emergent Hall effect. This enhanced non-adiabaticity is
only present in two- and three-dimensional magnetic textures such as vortices
and skyrmions and absent in one-dimensional domain walls, in agreement with
experimental observations.
