How to Make magnets float down a steel tube

Mr.G in the episode 3 of "Summer snow fall" explain the experiment for eddy currents and lenz law by using general house hold items like copper tubes of different dia., 2-neo themium magnets attached together and a ball bearing magnet. At first he took the big diameter copper tube and drop the neo-themium magnets, they fall slowly without touching the surface of the copper tube as they are like freely falling from space with less gravity, for the next time he took small diameter copper tube and drop the ball bearing magnet into it, as it also falls freely from the space without touching the surface of the tube but slowly. By this experiment he explained easily how eddy current and lens law work also it is easy to understand by doing the experiment at home.
