  Spatial gaseous structures in the Beta Lyrae system have been studied with
the fact of change in the longitudinal component of the donor's magnetic field
during the orbital period in mind. The investigation was based primarily on the
study of the dynamics of the circumstellar structures surrounding the binary
system as a whole. The special emphasis was placed on the study of complex
helium lines, in particular those arising from metastable levels. A number of
different observable facts from the ultraviolet to the red spectral region were
analyzed. The configuration of the donor magnetic field is a factor that not
only enhances mass transfer and influences the formation of spatial gas
structures between stellar components but, to some extent, also affects the
outflow of matter and the formation of external gas structures around this
interacting binary system. Together with previous articles
\citep{Skulskyy2020a, Skulskyy2020b}, the pieces of evidence of this work,
confirming the reflection of magnetically controlled matter in circumbinary
structures, define the basis for a coherent picture of the mass exchange
between components and outflows of matter outwards
