It has been shown previously that texture can be achieved in Bi2Sr2CaCu2Ox (Bi2212) bulk and tape conductors by applying a background magnetic field during the partial-melt stage. In this paper, we report on the texturing of low aspect ratio multifilamentary Bi2212/AgMg wires that were partial melt processed in a 12 T background magnetic field. To determine the effects of the applied magnetic field on the transport properties, the critical current was measured using the four point method. Transport measurements were carried out in magnetic fields up to 5 T with varying magnetic field angle. It was found that some texture is induced, resulting in electrical properties that vary with magnetic field orientation.
