How long would it take for it to lose the inertial momentum? Or drop to a sufficient level such that the speed of the earth is greater? I'm out of my depth here.

I saw a great video on YouTube on magnetic levitation. The spinner remains suspended in the air above the magnet. If the earth is rotating at 460 m/s why doesn't the spinner fall to the ground? Surely the magnet would move away due to the rotation of the earth, thus the spinner would eventually fall. As far as I can tell there is only gravity and the magnetic force acting on the spinner no lateral forces.
