直接测量三种不同的实验配置，并与二维流体理论的轴向力从磁膨胀电流自由等离子体。直接测量仅由扩展场产生的力分量，并将其识别为由于电子抗磁漂移和磁场的径向分量而由方位电流产生的轴向力。理论很好地描述了实验测得的力。
The axial force imparted from a magnetically expanding current-free plasma is directly measured for three different experimental configurations and compared with a two-dimensional fluid theory. The force component solely resulting from the expanding field is directly measured and identified as an axial force produced by the azimuthal current due to an electron diamagnetic drift and the radial component of the magnetic field. The experimentally measured forces are well described by the theory.
