Yes, there are a number of interesting things which might clarify whether this effect is more than a curiosity. If there is some high frequency, and I see what you are talking about on the scope, then it might be able to light a neon bulb or CFL.
Or maybe an LED attached to spinning cube magnet so that the leads are on opposite poles? From: [email protected] Jones, I noticed high frequency transients on videos scope screens at the peaks of the traces. I think they are real and may they are electrical interference of dc motor (this can be ruled out because they could be present all all videos) or result of mechanical ultrasonic ringing of magnet or a related to behaviour of Nd magnets when they receive magnetic impulses. I will investigating it tomorrow. These transients can be clearly seen on video dated Nov. 7.

OTH, I am monitoring the current driving the motor. Sometimes current drops up 8% when floating magnet get stablely spinning on the air compared motor running stand alone. This not really expected while the extra signifant vibration caused by floating magnet interaction. This vibration would normally cause stress on rotor and would increase the friction. For example 63 mA to 57 mA at 25 V.
