| 摘 要： | 在低频弱磁场下，铁磁性材料中由于畴壁的振动使周围磁通量改变,从而在材料内部形成微观涡流，导致损耗，这种因畴壁位移引起的微观涡流损耗对金属铁磁材料尤其突出，甚至超过通常意义下的涡流损耗。

| Abstract: | When ferromagnetic materials are presented in a weak alternative magnetic field with low frequency,the domain walls within the materials will vibrate around their equivalent position.The eddycurrent loss caused by the movement of magnetic domain wall is discussed in this article,and the loss is comparative to or even greater than that in the material without domain wall movement.This situation is especially essential for metallic ferromagnetic materials. |

| Keywords: | micro-eddy current domain wall movement loss |
