Evolution of the traveling distance of the heads of bubbles (upper panels) and the energy contained within the jetted bubbles (lower panels) in the two sets of runs discussed in Sects. 4.1 and 4.2. The bubble region is identified by a density lower than 5 × 10⁻²⁷ g cm⁻³ and a toroidal magnetic field stronger than 10⁻⁹ G. The subsequent mixing between the bubble region and the ambient gas can result in an upward trend in the energy curves. Different line colors represent different runs. The vertical lines denote when the jets are shut off.
