A new experiment allowing the study of static domain boundary dimensions in bistable microwire is proposed. In this experiment a static domain boundary is created by an inhomogeneous axial magnetic field. The changes in axial magnetic flux due to the presence of this boundary were measured along the microwire using two pick-up coils. Experimental results were compared with a simple theoretical model. For Fe_{77.5}Si_{7.5}B_{15} microwire with total diameter of 30 μm and metal nucleus diameter of 15 μm, good agreement between theoretical and experimental data was obtained for an axial dimension of the static domain boundary about 200 times larger than the diameter of the wire metallic core.
