The flow control of NaCl aqueous solution was examined by applying gas-liquid interface deformation induced by magnetic fields. Detailed studies of the dependence of flow velocity and concentration on the change in flow rate were carried out. In this experiment, with a flow on the order of 100 ml/min, the change in flow rate was measured under magnetic fields up to 10 T. The flow rate decreased due to gas-liquid interface deformation at magnetic fields of about 6 T or more; the decrease in flow rate was approximately 23% at most. The change in flow rate was dependent on the flow velocity and not on the concentration. In addition, the possibility of using gas-liquid interface deformation induced by magnetic fields as a new application for controlling the flow of NaCl solution without contact was discussed.
