Imagine you have a length of copper pipe and two small solid cylindrical objects - one made of aluminum (or plastic, if you wish) and the other is a bar magnet. You may assume that the aluminum cylinder and the bar magnet have the same size (small enough to fit through the copper pipe without touching the sides) and mass. Now imagine dropping the aluminum through the copper pipe, and then dropping the bar magnet through the copper pipe. Do...
