At this small scale and due the field geometry of the larger lifter magnet the weak diamagnetism of copper is sufficient for holding the tiny cube magnet in a stable levitation position. Be aware that this is not an eddy current levitation but diamagnetically stabilized levitation. The levitation is free and stable and needs no energy input. What you can see is of course eddy current damping when one trys to misalign the floating magnet. The levitation height is only about 0.3 mm. The match head is for size comparison.
