| contents | Relaxation of the magnetic field in rigidly rotating quark-gluon plasma is studied. It is shown that the infrared modes satisfying $k < |m|Ω$ and $k< |m\pm 1|Ω$, where integer $m$ is the projection of the orbital angular momentum along the rotating axis and $Ω$ is the angular velocity, are unstable. The instability onset time and the magnetic field growth rate are computed for a standard initial profile of the magnetic field. Given the present phenomenological values of $Ω$ and electrical conductivity $σ$ the instability is not expected to be a significant factor in the field's time evolution. |
