The axisymmetric slow viscous MHD flow of a conducting liquid about a solid insulating body of revolution, translating parallel with bothits axis of revolution and a uniform magnetic ambient field, is considered. A new boundary formulation is proposed to efficiently calculate such a flow subject to a non-uniform Lorentz body force. The advocated procedure, also providing the force exerted on the body, is illustrated for a sphere translating either in an unbounded liquid or along the axis of a solid cylindrical no-slip tube bounding the liquid.
