south magnetic pole

基本解釋

And Why can't we find an isolated magnetic north or south pole?
爲(wèi)什麼我們找不到單獨(dú)存在的南磁極或北磁極的磁極呢？
This means that the magnetic North Pole changes place with the magnetic South Pole.
這意味著磁北極的變化與南極磁場(chǎng)發(fā)生。
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，如果你有很多錢，你甚至可以把原子分成一些亞原子粒子：質(zhì)子、中子和電子，但即使是這些小磁躰，也還是有南北磁極。
