Yes I was wondering about that. Magnetic force follows a power law, so you would think the upward force, once it's at the point of balancing the weight of the turntable, might be almost as rigid as a solid connection. Although it would be less so, the lighter the turntable was, for a given magnetic field strength. But then you would probably incur a "jumpiness/bounciness" penalty. Rather an interesting design problem actually.
