They hit the bottom at about the same time. Drop them into the copper pipes and the magnet takes longer to reach the bottom. The magnet makes a current and a magnetic field on and inside the copper pipe. The magnetic field slows the falling magnet. The air moving across the top of the wing is moving faster because of the curved surface.
Fast air equals low air pressure.
The slower air on the underside of the wing results in high air pressure that lifts it up. The force of gravity acts along the arch and it is supported by its own weight. Put one hand on the aluminum pipe and the other on the copper pipe. Watch as the needles move. The energy to maintain this current comes from the chemical reaction between the metals and the moisture on your hand, much like the acid in a battery.
