The steady two-dimensional flow of an incompressible fluid with finite electric conductivity is discussed. It is assumed that the magnetic field and velocity vectors are in the plane of flow and each reaches a constant value at infinity. Formulas were obtained for the cases where: the undisturbed velocity and magnetic field are parallel: the magnetic Prandtl number, lambda = /K, is unity, where is the kinematic viscosity, and K is the magnetic viscosity of the fluid; and the Stokes flow in which the undisturbed velocity U is very small compared to the Alfven-wave propagation speed a. The formation of two wakes. instead of one. is observed, and, in general, the points are in different directions. It was found that the upstream wake appearing for U < a is dominant in the total mass flux and the total magnetic flux along the wake compared with the downstream wake, except where a/U>> /sup s/sup 1/>s, in which both wakes have equal strength. The drag and lift for an insulating circular cylinder are determined. (B.0.G.)
