  The behavior of a microdrop of dielectric liquid suspended in a magnetic
fluid and exposed to the action of electric and magnetic fields is studied
experimentally. With increasing electric field, the deformation of droplets
into oblate ellipsoid, toroid and curved toroid was observed. At the further
increase in the electric field, the bursting of droplets was also revealed. The
electrorotation of deformed droplets was observed and investigated. The
influence of an additional magnetic field on the droplet dynamics was studied.
The main features of the droplet dynamics were interpreted and theoretically
examined.
