Experiments aimed at an investigation of the influence exerted by a magnetic field on the resistance associated with the circumfluous motion of mercury around conductive solids are described in the first part of this work. It is learned that when good electrical contract is present between the mercury and the solid that it flows around, the resistance of the solid increases with an increase in its electric conduction. The second part of this text is devoted to a study of the influence exerted by a magnetic field on the distribution of pressure along a circular cylinder. It is shown that when a magnetic field is applied, pressure along the front portion of the cylinder increases, so that the pressure coefficient in place at the leading stagnation point becomes greater than unity. Pressure along the afterbody of the cylinder decreases. The resistance increase resulting from pressure variation accounts for 40 to 50 percent of the increase in total resistance.
