Electrohydrodynamic and magnetohydrodynamic convection

As (Rosensweig, 1985) points out, the interaction of electromagnetic fields and fluids has been attracting increasing attention due to applications in many diverse areas. He writes that the subject may be divided into three main categories:1.Electrohydrodynamics (EHD), the branch of fluid mechanics concerned with electric force effects;2.Magnetohydrodynamics (MHD), the study of the interaction between magnetic fields and fluid conductors of electricity; and3.Ferrohydrodynamics (FHD), which deals with the mechanics of fluid motion induced by strong forces of magnetic polarization.
