Dynamics of a dielectric droplet suspended in a magnetic fluid in electric and magnetic fields

摘要

The behavior of a microdrop of dielectric liquid suspended in a magneticfluid and exposed to the action of electric and magnetic fields is studiedexperimentally. With increasing electric field, the deformation of dropletsinto oblate ellipsoid, toroid and curved toroid was observed. At the furtherincrease in the electric field, the bursting of droplets was also revealed. Theelectrorotation of deformed droplets was observed and investigated. Theinfluence of an additional magnetic field on the droplet dynamics was studied.The main features of the droplet dynamics were interpreted and theoreticallyexamined.
