An exemplary retrospect on two-dimensional metrology applied to electrical sheet steel is presented. First the history of this subject before the starting of this workshop series is considered, i.e. the time of the mechanical methods of d.c. rotational hysteresis and loss measurements and of inductive-mechanical methods of a.c. loss measurements. It is followed by the field-metric metrology of a.c. rotational magnetic phenomena. This method underwent a rapid increase of application due to the fast development of electronics for the excitation and data acquisition of magnetic field quantities in the 1970s and 1980s. Initiated by this development, the workshop series started shortly after in 1990. Besides the main item of the workshop, the metrology, the items modelling, theory and applications did enter the scope of the workshop soon. This retrospect focuses on the metrology of magnetic properties under two-dimensional excitation.

Przedstawiono retrospekcję badań dwuwymiarowych w dziedzinie blach elektrotechnicznych z uwzględnieniem osiągnięć workshopów. Początki związane były z metodami mechanicznymi. Następnie wprowadzono metody związane z pomiarem składowych pola magnetycznego i indukcji. Pomocą był tu rozwój elektroniki umożliwiający łatwą akwizycję wszystkich składowych. W związku z dynamicznym rozwojem tej dziedziny w latach dziewięćdziesiątych rozpoczęto organizację workshopów poświęconych tym zagadnieniom. Obok pomiarów zajmowano się też modelowaniem, teorią i zastosowaniem.
