Continuous casting is becoming standard practice in industrial metallurgy. Some subsequent process could perhaps be saved and the quality of solidified ingots improved if the non-contacting shape control method was developed. In this paper we present the results of an experimental investigation of a jet of mercury emanating from circular and rectangular non-conducting nozzles situated at the end of electromagnetic pole pieces where the magnitude of the magnetic field decreases to zero. The shapes of the free surface of the jet are measured by a spot electrode probe under various experimental conditions. In such a non-uniform magnetic field, there is a longitudinal, recircular current flow which induces the cross-sectional force and increases the jet aspect ratio b_j/h_j. The value of the aspect ratio of the jet issuing from a rectangular nozzle 15 mm wide and 3 mm high increases up to 80.
