Abstract:
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.
