INSTABILITY OF A MAGNETIC FLUID JET IN A PERPENDICULAR MAGNETIC FIELD
The results of experimental investigation of instability and breakup of a vertical magnetic fluid jet under the action of a perpendicular external stationary uniform magnetic field are presented in the article. It is shown that the action of a perpendicular magnetic field stimulates the instability development. The length of the uninterrupted jet section was measured as a function of the magnetic field strength and the jet velocity. It is shown that in a magnetic field the jet deforms taking undulate configuration. The jet deformation amplitude (the maximal deflection from a vertical) was measured as a function of the magnetic field strength and the jet velocity. The theory of the instability of a magnetic fluid jet in a perpendicular magnetic field is developed in the linear wave approximation. The comparison of the experimental and theoretical data demonstrating the satisfactory agreement of the theory and the measured results is performed.
