Abstract
The flow of mercury in the wake behind a circular cylinder with axis parallel to a magnetic field is investigated. We give measurements of the mean and the fluctuating characteristics of the flow by means of a thermoanemometer and a conduction anemometer with a three-electrode pick-up. It is shown that, in a sufficiently strong magnetic field, the flow acquires properties characteristic of two-dimensional turbulent flows.
