Well, with a lot of money, you can cut even the atom into to subatomic particles: protons, neutrons and electrons, but even these little magnets still always have one North and South magnetic pole.
好吧，如果你有很多钱，你甚至可以把原子分成一些亚原子粒子：质子、中子和电子，但即使是这些小磁体，也还是有南北磁极。
Earth is a very large magnetic field, the magnetic field lines from the North Pole, the Earth's surface into the South Pole.
地球是一个无比巨大的磁场，其磁力线由北极出来，经地球表面而进入南极。
This means that the magnetic North Pole changes place with the magnetic South Pole.
这意味着磁北极的变化与南极磁场发生。
Magnetic saturation effect on the saliency is used to distinguish the north magnetic pole from the south.
磁饱和影响的显着性是用来区分从南部的北磁极。
Such nuclei spin on an axis like miniature tops, giving rise to a magnetic moment, which means the nuclei act as if they were bar magnets with a north and south pole.
这种原子核像缩微的陀螺围绕一根轴线自旋，产生磁性，像具有S极和N极的磁铁棒一样。
Such nuclei spin on an axis like miniature tops, giving rise to a magnetic moment, which means the nuclei act as if they were bar magnets with a north and south pole.
这种原子核像缩微的陀螺围绕一根轴线自旋，产生磁性，像具有S极和N极的磁铁棒一样。
