A plate is immersed in a conducting flow with parallel velocity and magnetic field. The fluid is assumed inviscid and weakly diffusive. A perturbation is created in the plate, which in its turn modifies the background flow by generating a boundary layer. When the perturbation is variable in time, the layer is shown to possess a complex inner structure. The perturbed quantities decrease exponentially in time, while their spatial behavior is oscillatory and decreases with the inverse of the square root of the distance to the plate. The Lorentz force is shown to agree with the behavior of the perturbed density.

在传导流中由可变磁场产生的边界层上

将板浸入具有平行速度和磁场的传导流中。假定流体是无粘性的且微弱扩散的。板中会产生扰动，进而通过生成边界层来修改背景流。当扰动随时间变化时，表明该层具有复杂的内部结构。扰动的量随时间呈指数下降，而它们的空间行为却是振荡的，并且随着到板的距离的平方根的倒数而减小。洛伦兹力被证明与扰动密度的行为一致。
