Abstract
Various models are constructed to describe magnetic fluids. A system of equations governing the behaviour of a magnetizable medium in electromagnetic fields is written. The medium is assumed to consist of several phases and components, each one having its own temperature and being magnetized in compliance with its own law. Equations governing the behaviour of magnetizable surface-active substances (magnetic surfactants) is derived. Proceeding from these equations, corresponding boundary conditions relating values of parameters of bulk phases are derived. The effect of a film of a magnetic surfactant on the motion of a nonmagnetic liquid drop and solid particle in another nonmagnetic liquid is considered. An expression was obtained for the drop velocity in terms of the magnetic field gradient as well as of the parameters of bulk phases and magnetic surfactant film. The effect of a magnetic surfactant on the damping of surface waves propagating along the surface of a common nonmagnetic liquid is investigated. Damping coefficients of surface waves are calculated for different orders of magnitude of the quantities involved.
