此外，由于制作这微粒的氧化铁是带有磁性的，就可以通过磁场来旋转其方向。
Moreover, since the form of iron oxide used to make the droplets is magnetic, a magnetic field can be used to rotate them.
所连接的直流电动机可以这样调整使得其转速高于同步转速且旋转方向与定子旋转磁场的方向一致。
The coupled dc motor can be adjusted so that the speed of the system is higher than the synchronous speed and the system rotates in the same direction as the stator rotating field.
这些破坏了地球的磁场和扭转地球磁极'旋转方向。
These disrupt the Earth's magnetic field and reverse the Earth's magnetic poles' rotational direction.
