Potential field extrapolation (left panels) and linear MHS field extrapolation (right panels) based on the SO/PHI-HRT vector magnetic field data at 05:04:19 UT. Panels (a) and (b): Top views, with magnetic field lines marked in blue. Panels (c) and (d): Top view of the magnetic field structures of the jets, within the FOV outlined by the red squares in the top panels. Panels (e) and (f): Side views of the magnetic field structures of the jets. In panels (c)–(f), the blue curves represent open field lines, and the red curves represent closed field lines.
