Abstract

Turbulent diamagnetism results in an expulsion of large-scale magnetic field from regions with a high intensity of turbulent motions (see, e.g. [1]): a turbulent conductive fluid behaves like a diamagnetic with an effective magnetic permeability μ ∝ β−1/2, with β being the turbulent magnetic diffusivity. This phenomenon can be described as a transport of the largescale magnetic field at a velocity which is proportional to — ▽β.
