您要查找的是不是:
- Occasionally, however, the dipole part of the field reverses, causing the locations of the north and south magnetic poles to switch. 不过,有时候磁场的偶极部分会倒转,导致了北磁极和南磁极的位置转换。
- It has been suggested that birds can sense the magnetic lines of force stretching from the north to the south magnetic poles of the earth . 有人提出:鸟能感觉到从地球北极通向南极的磁力线。
