Abstract
A study is made of the flow of an electrically conducting liquid with a sharply changing conductivity of the wall, perpendicular to the applied homogeneous magnetic field. It is established experimentally that, in this case, in a plane perpendicular to the field, a non-monotonic velocity profile is formed. It is shown that the reason for its formation is the presence of a gradient of the component of the electric current along the field.
