Abstract
We have investigated the influence of stationary velocity fields, twists of the field lines and changes of gas pressure within flux tubes on the interchange instability of magnetic flux tubes. A small flux tube is found to be stable. All three factors mentioned above can stabilize tubes with all fluxes. We estimate that, for the solar case, a change of gas pressure in flux tubes plays an important role in stabilizing magnetic flux tube.
