The article is concerned with the study of the effect of a coplanar magnetic field on the flow of liquid metal in a rectangular channel. Results of temperature fluctuation intensity measurements in the channel cross-section are given at a different magnetic field influence. To assess the influence of thermogravitational convection on the flow, two regimes were implemented: downward and upward flow with a low-valued heat flux. As a result, in the experiment it was possible to decrease the influence of natural convection and obtain a ``pure'' magnetic field influence. The obtained data were generalized as an exponential dependence of the degree turbulence suppression by the coplanar magnetic field on the regime parameters (Re, Ha). Figs 9, Refs 12.
