If I could I would rather prepare different experiment based on proposed one. Upper magnet would be higher and around it a big coil made of tiny wires of appreciated self-inductance would be placed to detect any anomaly in perfect magnetic field around. Of course no current will be measured when a magnet below is not spinning. No current would be probably also measured when a magnet below would be slowly increasing it's speed or rotate fast but monotonously.Then I will somehow stop abruptly that lower magnet and search for any current or voltage generated in sensing coil above.
