We put a valve on the bottom of the tube, this stop water from coming in the tube and the water in the tube evaporates and the valve opens and the magnet goes up and bammo we got perpetual motion(or a really horrible failure and a travesty to science)
The weight of the float+magnet would overcome any weak upward force exerted by capillary action.
