The linear steady convection of a fluid layer between rigid thermally and electrically non-conducting walls is investigated from three different stand-points: 1) convection of a rotating fluid, 2) magnetoconvection and 3) magnetoconvection in a rotating fluid. The new dependences of the critical Rayleigh and wavenumbers on the Taylor and Chandrasekhar numbers are discussed.
It is shown that in contrast with fluids in the same conditions but with walls of different thermal conductivity, the fluid in the present case is always the most thermally unstable for every Taylor and Chandrasekhar numbers. Moreover, in the present case the horizontal scale of the cell pattern is always the largest. Also, when rotation and magnetic field act simultaneously, in the region of strong interaction the stability of the magnetofluid is highly decreased and the critical wavenumber is always zero.
