Line integral convolution of the magnetic field, in the plane of the image. Colourmaps are for visualisation only. The black hole is marked as a black cross, and the instantaneous jet direction is shown with an orange line. The white circles have radii of 50 (dashed) and 100 (solid) kpc, respectively. In the presence of conduction, the HBI re-orients the magnetic field in a tangential configuration outside the central region.
