Rayleigh-Taylor Instability of Two Superposed Conducting Fluids in the Presence of a Variable Magnetic Field and Suspended Particles

The instability of two superposed fluids in the presence of suspended particles is studied. It is found that the system is unstable for sufficiently long waves, however large the applied magnetic field may be, provided the initial configuration is top-heavy density wise. Also, the potentially stable system remains stable for the case of two superposed fluids in the presence of a variable magnetic field and suspended particles.
