We present an experimental study of a liquid metal flow in a rectangular channel under the influence of an inhomogeneous magnetic field. This investigation addresses a fundamental problem of liquid metal magnetohydrodynamics relevant to electromagnetic braking techniques in continuous steel casting and Lorentz force velocimetry. Utilizing local velocity and electric potential measurements, we identify three distinct flow regions: turbulence suppression region, vortical region, and wall jet region. In the turbulence suppression region, the inhomogeneous magnetic field significantly brakes the incoming flow and transforms the velocity profile from flat to an M-shaped form. We observe a marked decrease in velocity fluctuations within this area. In the vortical region, where the magnetic field is strongest, the flow exhibits large-scale time-dependent vortical structures at certain control parameter values. In the wall jet region, downstream of the magnetic system, two sidewall boundary layers generate velocity fluctuations up to 25% of the mean flow, closely resembling wall jets observed in classical hydrodynamics. Our experimental data provides a comprehensive database for validating numerical simulations and turbulence models.
