Magnetic Fluid Structural Transformations in Electric and Magnetic Fields

Periodic structural lattices formed in thin layers of an originally uniform magnetic fluid exposed to a constant electric field were studied experimentally. Peculiarities of their transformations under the effect of an additional magnetic field were described. The structural transformations and the development of an electrohydrodynamic instability in an aggregated magnetic fluid subjected to both alternating electric and constant magnetic fields were investigated. The observed patterns of the light diffraction on the studied structures were reported.
