Air Cavity Capture by a Flat Channel with Magnetic Fluid in an Annular Magnet

  • PHYSICS OF MAGNETIC PHENOMENA
  • Published:
Russian Physics Journal Aims and scope

The paper discusses research on visualization of air cavity capture and transportation in a flat channel filled with magnetic fluid and located along the annular magnet axis. It takes the results of the model theory of “weakly magnetic medium” based on construction of a system of isolines of magnetic field intensity module (Н = const) for the magnetic fluid filling the tube and compares them to the air cavity image produced in a thin fluid layer. Distinctive features of the stage-by-stage air cavity capture are theoretically explained for different magnetic fluid concentrations. The results can be useful in solving practical microhydraulics problems.
