Evolution of a stochastically homogeneous magnetic field advected by an incompressible turbulent flow with large magnetic Prandtl numbers is considered at scales smaller than the Kolmogorov viscous scale. It is shown that, despite the unlimited growth of the magnetic field, its feedback on the fluid's dynamics remains negligibly small.

在小规模的湍流磁场中不可能有反馈

在比Kolmogorov粘性标度更小的标度上，考虑了由具有大Prandtl数的不可压缩湍流引起的随机均匀磁场的演化。结果表明，尽管磁场无限增大，但其对流体动力学的反馈仍然很小。
