Recent results on the study of a liquid metal flow around an insulating cylinder with constant aligned magnetic field are presented. From the experimental point of view, a special type of differential pressure transducer using strain gauges is described. The results obtained with mercury as liquid metal are presented for an interaction parameter N ranging from O to approximately 8. The stabilizing effect of the magnetic field on the boundary layer separation is shown. Pressure distribution around the cylinder as well as the overall pressure drag coefficient CD are given for different values of N. The last section presents analytical calculations of the flow distribution of an inviscid fluid when N << 1. The theoretical results are in good agreement with these experimental results.
