实验室实验表明，高速等离子体流从两个脚点的拱形磁通量管，导致散装等离子体运输到通量管和持久的轴向准直，即使通量管加长和扭结。测量的流量与预测的环向力和准直模型，包括基本的MHD力。这些力量预计将驱动等离子体加速在其他开放通量配置与拱形的几何形状，如那些在太阳表面上发现的。
Laboratory experiments demonstrate high-speed plasma flows from both footpoints of arched magnetic flux tubes, resulting in bulk plasma transport into the flux tube and persistent axial collimation even as the flux tube lengthens and kinks. The measured flows are in agreement with the predictions of hoop force and collimation models involving fundamental MHD forces. These forces are expected to drive plasma acceleration in other open flux configurations with arched geometries, such as those found on the solar surface.
