在具有剪切的旋转磁化等离子体柱中，交叉场电流可以由惯性机制和交叉场粘性引起。考虑到这些机制，可以计算圆柱形几何形状中不可约的径向电流消耗作为旋转频率的函数。由此产生的表达式提出了新的可能性，通过控制等离子体的密度和温度分布的电场分布定制。
In a rotating magnetized plasma cylinder with shear, cross-field current can arise from inertial mechanisms and from the cross-field viscosity. Considering these mechanisms, it is possible to calculate the irreducible radial current draw in a cylindrical geometry as a function of the rotation frequency. The resulting expressions raise novel possibilities for tailoring the electric field profile by controlling the density and temperature profiles of a plasma.
