Two semi-infinite incompressible and immiscible viscous fluids of infinite lateral extent are considered in the gravity field. One of them is ferromagnetic and the other is a usual Newtonian liquid. Such a system is submitted to a magnetic field normal to the reference flat surface, which separates the two bulks. Developing the linear stability analysis, we show that the Rosensweig critical values for transverse waves remain unaffected by a solutal or thermal Marangoni instability.
