Visualization of the evolving roles of the magnetic field over the scales presented in Figures 8 and 9. Visualized are streamlines based on the detected magnetic field morphologies in Figure 8 using a line convolution algorithm for vector fields (e.g., Cabral & Leedom 1993). From left to right are envelope-to-core scale (first and second), global-collapsing-core scale (third), local-collapsing-core scale (forth), and accreting-dust-lane scale (fifth). No visualization is shown in black patches with too sparse sampling in the original data, which does not allow us to construct a connected convolution.
