8. Euler's Pendulum

Take a thick plate of non-magnetic ma­terial and fix a neodymium magnet on top of it. Suspend a magnetic rod (which can be assembled from cylindrical neo­dy­mium magnets) underneath it. Deflect the rod so that it touches the plate only with highest edge and release it. Study the motion of such a pendulum under various conditions.

取一非磁性材料的厚板并在其上固定一个钕磁铁。在板下方悬挂一根磁性棒(可由一系列圆柱形钕磁铁组装而成)。偏转此棒使其只有顶部的边缘与板解除，然后释放它。研究这个摆在不同条件下的运动。
