中文：目的
磁力線是人類想像出來描述磁場的抽象概念，如今我們用簡單的器材將磁力線以立體的方式呈現在我們面前。 實驗 實驗裝置： 壓克力盒：從壓克力方盒中鑽兩個洞，黏上一圓管，盒內灌入油液及鐵粉。 強力磁鐵：數個長型圓柱狀強力磁鐵。 封閉磁力迴線： 先將壓克力方盒均勻搖動，使其內鐵粉均勻分布於油液中。 將方盒平放後，立即插入磁鐵棒。 觀察盒內鐵粉磁力線成型的過程。 相斥磁力線分布： 先將壓克力方盒均勻搖動，使其內鐵粉均勻分布於油液中。 將方盒平放後，將兩根鐵棒以同極相對，從兩旁分別插入盒內。 觀察盒內鐵粉磁力線成型的過程。 原理思考 什麼是磁力線的概念?它跟磁場又是什麼關係呢？ 更多資訊請參考https://goo.gl/1rLWrA 歡迎聯絡我們：ncusciedu@g.ncu.edu.tw（中央大學科學教育中心） |
