Dramatic eruption of an arched magnetic flux rope in a large ambient plasma has been studied in a laboratory experiment that simulates coronal loops. The eruption is initiated by laser generated plasma flows from the footpoints of the rope that significantly modify the magnetic-field topology and link the magnetic-field lines of the rope with the ambient plasma. Following this event, the flux rope erupts by releasing its plasma into the background. The resulting impulse excites intense magnetosonic waves that transfer energy to the ambient plasma and subsequently decay.
在一个模拟日冕环的实验室实验中，研究了一个大的背景等离子体中拱形磁通量绳的剧烈爆发。这种爆发是由来自绳脚点的激光产生的等离子体流引发的，这显著地改变了磁场拓扑结构，并将绳的磁场线与背景等离子体连接起来。在此事件之后，通量绳通过将其等离子体释放到背景中而爆发。由此产生的脉冲激发强烈的磁声波，将能量传递给背景等离子体，随后衰减。
