The object in this study is to observe directly the magnetic domain behavior in a toroidal core of ultra thin grain oriented silicon steel under applying rf magnetic field and to make clear the effect of domain wall number and velocity of the domain wall movement on the coarse loss. (1) We can observe the dynamic domain behavior up to 10kHz on the core surfaces and obtain the domain wall number and the velocity of domain wall movement from this observation. (2) By forming grooves perpendicular to the roll direction on the steel surface, the domain wall number in increased and the core loss is decreased.

本研究的目的是直接观察超薄晶粒取向硅钢环形磁芯在射频磁场作用下的磁畴行为，明确畴壁数和畴壁运动速度对粗损耗的影响。(1)我们可以在芯表面上观察到高达10kHz的动态畴行为，并由此观察获得畴壁数和畴壁移动速度。(2)通过在钢表面形成垂直于轧制方向的沟槽，可以增加磁畴壁数，降低铁损。
