SummaryThe electromagnetic forces in the flow of an electrically conducting fluid in the presence of a magnetic field are non-conservative and therefore produce vorticity. The simple case of uniform efflux of a conducting fluid from the surface of a magnetized sphere is studied. Two methods are developed: one gives the solution for small conductivity and any magnetic intensity, the other gives the solution for small magnetic intensity and any conductivity.

Abstract

SummaryThe electromagnetic forces in the flow of an electrically conducting fluid in the presence of a magnetic field are non-conservative and therefore produce vorticity. The simple case of uniform efflux of a conducting fluid from the surface of a magnetized sphere is studied. Two methods are developed: one gives the solution for small conductivity and any magnetic intensity, the other gives the solution for small magnetic intensity and any conductivity. The case evaluated in detail is that for a magnetic dipole situated at the centre of the sphere. The magnetic lines, streamlines and vortex lines are found in closed form and shown in figs. 1 and 2 for two values of the parameters involved.
