Capture of air cavity flat channel with magnetic liquid in a ring magnet
Studies on the visualization of the capture and transport of an air cavity in a flat channel filled with magnetic fluid and located along the axis of the ring magnet are discussed. The results of the model theory of a “weakly magnetic medium” based on the construction of a system of isolines of the magnetic field strength module (H = const) for a magnetic fluid filling a tube are compared with the image of an air cavity obtained in a thin liquid layer. The features of phased capture of the air cavity for magnetic fluid are theoretically explained. The results can be useful in solving practical issues of microhydraulics.
