Birds, turtles and even bacteria Orient to the earth's magnetic field lines.

鸟、乌龟甚至细菌都是通过地球磁场线来定位的。

The orange and blue lines depict the opposite north and south polarity of Earth's field lines.

橙色和蓝色的线条分别表示地球磁场中南极、北极两种相反磁性的磁力线。

If we put a dipole that has the freedom to move, we put that dipole in an electric field, it will align itself with the field lines.

若我们将偶极释放到自由空间中，比如说放到电场里，他们会自动排序按同一方向。

Somewhere along the way, something must be happening that is alien to the neat picture of plasma and field lines moving together.

ECONOMIST: Hot stuff

The magnetic field lines are like the two lanes of traffic on a busy road: close together, but pointing in opposite directions.

The same thing happens with the magnetic field lines, which suddenly reconnect, resulting in a hole a few kilometres wide in the armour of the magnetosphere, through which plasma can spill.
