馬上就能判斷N極跟S極
I thought about it for a long time, and then I had an idea,
我想了很久，後來靈機一動，
Think of the compass
想到指南針
to determine the N pole and S pole of the magnet
就可以判斷磁鐵的N極跟S極
What’s the rationale for that
N pole of magnet
磁鐵的N極
In fact, it is taken from the capital of the first letter of North
其實是取自於North第一個字母大寫
Magnet S class
磁鐵的S級
In fact, it is taken from the capital of the first letter of South
其實是取自於South第一個字母大寫
那用的是什麼原理呢

Please pay attention to this place
這個地方請大家注意一下
The distance between the magnet and the compass should not be too close
磁鐵跟指南針之間的距離不要太近
Otherwise there will be no response
要不然會沒有反應
you have to give it some distance
你要給它間隔一段距離
The point is that when you measure
重點就是說你在量測的時候
You don’t get too close, you give it some distance
你不要離太近，你要給它間隔一段距離
This way the measurement will be more accurate
這樣子的話量測會比較準
