QUANTIFICATION OF THE LOCAL MAGNETIZATION ON NONORIENTED SHEETS - APPLICATION TO THE STUDY OF THE INFLUENCE OF EXTERNAL STRESS

In order to study the physical influence of the mechanical actions on the magnetic performances on non-oriented silicon-iron sheets, an expe rimental bench to visualize magnetic domains and a quantitative method ology to determine easily the local magnetization have been developed. Their use, in the case of a sheet under stress prove, by the diversit y of the local magnetization, the great interest of such a systematic study.
