阿拉果圆盘是发现电磁感应中最非凡的实验，也是大学物理中优质的交叉学科案例.本文介绍了现代阿拉果圆盘实验的数学细节和实验装置简易搭建，在现代模式中使用转速表、转速调节器和电压表可快速地显示电磁阻尼与驱动效应，并选择了可置换不同金属材料圆盘或丝网的便捷模式，可促进其在课堂与实验教学中使用和推广.

Arago^,s disc is the most extraordinary experiment in the discovery of electromagnetic induction， and is also a high-quality interdisciplinary case in university physics. This paper introduces the mathematical details of modern Arago^,s disc experiment and the simple construction of experimental equipment. In the modern mode， the use of tachometer， speed regulator and electric manometer can quickly display the electromagnetic damping and driving effect， and the convenient mode that can replace disks or wire meshes of different metal materials is selected so as to promote its use and promotion in classroom and experimental teaching.
