Abstract

A linearized theory is presented for the response of magneto-fluid dynamic turbulence to an imposed strong magnetic field in the presence of gyrators such as the Coriolis force and the Hall effect. The analysis includes these two effects in a unified manner, and the directional energy transfer as well as the energy conversion between the mechanical and magnetic modes of turbulence are discussed under several simplifying assumptions. With a few examples, it is demonstrated that gyrators act to suppress the modal energy conversion on the one hand, and to equalize the directional partition of energies on the other.
