Figure 7

Shows the effect of the forces exerted on the micro-UFO depending on the distance between the “Lifter Magnet” and the “Pyrolytic Graphite”. Accordingly, as the distance increases, the total forces on z-axis decreases exponentially. Minimum levitation point when lifter magnet distance is 60 mm, 31.02 µm; maximum levitation point is 54 mm, 329.1 µm are calculated.
