The instability due to vertical temperature gradient is studied in a rapidly rotating horizontal layer of an electrically conducting fluid permeated by an azimuthal magnetic field, which linearly grows with distance from the vertical rotation axis. Both boundaries of the layer are rigid and perfectly ...
