We report an experimental study of the inhibition of the instability generated by a magnetic field applied perpendicularly to the surface of a magnetic fluid (the Rosensweig instability), by vertical vibrations of the fluid container. Our measurements are in quantitative agreement with a simple analytical model using the theory of Mathieu functions.
