Abstract
We studied the dynamics of non-magnetic droplets in magnetic liquids in microchannels with a “flow focusing” configuration under the action of an inhomogeneous magnetic field of an annular magnet. Two types of multiphase systems were studied: non-magnetic emulsions “oil in water”, “water in oil”, as well as “water in oil in water” and magnetic direct emulsions in which the magnetic liquid was used as a continuous phase. The dependences of the sizes of the generated non-magnetic inclusions on the flow rate of the continuous magnetic phase and the displacement of the magnetic field source relative to the dispersed phase supply connector horizontally along the channel axis are obtained.
