Abstract : The first-order magnetohydrodynamic (MHD flo of an incompressible conductive fluid about a small rigid sphere moving slowly in the direction of a uniform magnetic field was calculated. A perturbation ream-functio was computed from the zero-order velocity and magne ic fields which enables one to evaluate the increase in drag due to the interaction between the two fields. T E RAG INCR SE IS PROPORTIONAL TO THE SQUARE OF THE artmann number and is a simple ul ipl of the tokes drag value. Though the analysis is limi ed to very low Hartm nn numbers, the extension of the present method to higher magnetic fields and also to similar axi-symmetric MHD problems is discussed. (Author)
