“…Problems connected with the influence of the external axial MF were started to consider in Zhilin et al (2011), Shatrov and Gerbeth (2012), Ivochkin et al (2016). In Zhilin et al (2011) we showed that even the weak external MF of Earth can lead to the essential hydrodynamical effect-the rotation of conductive liquid with velocity up to ∼10 cm s −1 at the current about 40 A and formation of the second upward vortex. In Shatrov and Gerbeth (2012), authors gave an estimate of value for the external MF when the secondary vortex fully suppresses the main EVF, but in our opinion it was not quite correct.…”

Experimental and numerical results on the effect of an external vertical magnetic field (MF) on the structure of the flow which occurs when an electric current passes through a conducting medium between two hemispheres are presented. The experiments on the velocity measurement were carried out on the eutectic alloy In-Ga-Sn with the unique fiber-optic transducers. The fiberoptic technique for measuring velocity is described. Results on influence of the axial external MF on the flow are presented. The boundary curve separating the one-vortex and two-vortices flow modes depending on the current values through the experimental setup and the external MF was obtained. These results can be used in electrometallurgy for a priori estimates of the flow structure in the direct-current-arc furnaces.

The paper describes the application of the thermocorrelation method for measuring the velocity in a current-carrying liquid. An electrovortex flow occurs when the current passing through a conducting medium interacts with its own magnetic field. Measurements of the velocity of the turbulent electrovortex flow of the liquid metal (eutectic alloy In-Ga-Sn) were carried out in a hemispherical container in the range of currents of 100–450 amperes in the presence and absence of compensation of the Earth’s magnetic field. The efficiency of the thermocorrelation method in a current-carrying liquid has been demonstrated. The dependences of the axial velocity on the current and the velocity profiles along the axis were obtained. It was found that the presence of the Earth’s magnetic field leads to a significant decrease in the average value of the axial velocity in the entire range of currents.

“…The main conclusion was that the earth magnetic field had indeed a strong influence on the flow. Any analysis of an electrically induced flow should carefully account for the influence of external magnetic fields even as small as the one generated by the earth [21].…”
