摘要：
The measuring system designer for 3D magnetic field scanning is presented. As a sensor of magnetic field AMR magnetoresistive sensor has been used. The result of scanning can be presented in form o a colour map. Such map very well represents the grain structure of a material. This grain structure influences performances of the material, for example losses in the case of electrical steel. Investigations of the structure can be an useful tool for control of technology of magnetic material manufacturing as well as a non-destructive testing of material.
