The magnetic buoyancy instability in superimposed plasma layers with and without the horizontal magnetic field B under constant gravity is analysed for arbitrary angles between the perturbation wavenumber K and B on the basic of the linearized magnetohydrodynamic equations. The instability growth rate and the deformation of the lines of force as a result of the instability are investigated. From the results, it is argued that a flux tube of moderate width and length will tend to grow to form an isolated flux loop, although the interchange mode with a short wavelength perpendicular to B has the largest linear growth rate.
