You say "the field is bound to the magnet"?
Maybe you meant NOT bound to the magnet, and I agree with that.
I suggest that the axial field is not bound to anything and is free to rotate with the magnet or not. In this case the field is bound to the screen because this is where the least work would be done.
Some believe the field is locked to space, and rotating the monitor would show a field rotation on the screen.
Magnetic Field Axial Rotation
Experiment to show that the field of a permanent magnet does not rotate with the magnet along the B axis. -
You may also want to try rotating the disk with the ferrite in the opposite direction to rule out any affect of the ferrite becoming magnetic just from the close proximity to the magnet and simply directing the field into the hall sensor.
Demonstration of magnetic viscosity
http://gigaGauss.com A lump of ferrite is stuck to the rotor. As the ferrite approches the fixed fMagnet it becomes magnetic. How long does the magnetism last in the ferrite? Here we can see on t... -

The actual cause of this effect was later determined to be the Earth's magnetic field.
Because I live around 45 degrees north latitude, the magnet pull on the north magnets pole is mainly downward toward the ground. This additional pull is very strong and simply causes the north pole of the magnet to tend to rotate downward more than the south pole.
This effect would change depending on where you live on the Earth.
magnetic field on aluminum
Shows a difference between magnetic poles on an aluminum plate. Why would the direction of magnetic field lines cause any different reaction on an aluminum plate? -
That's interesting, It may actually be due to the earths magnetic field and could be verified by rotating the the entire setup on the table 180 degrees to see if this also changes the gain direction on the wheel.
Magnetically Assisted Pendulum

Per OC's recommendation I did perform this test which conclusively shows that a gain can be derived from the magnetically assisted pendulum. -
Considering the side effects of 90% of the new drugs on the market every year, the side effects of HGH seem like nothing serious especially in comparison to the benefits. HGH has far more potential to benefit even older people with quality of life and increased ability but is prohibited for this use because of unverified risks. Several drugs with known severe side effects are prescribed every day to help the older population but mostly to help the drug industry.

I agree, It is likely a thermal condition in the magnet where the colder area of the magnet becomes slightly stronger and since this is closer to the bottom and is also what's suspending the magnet, it becomes unstable and starts to rock and eventually rolls over.
At that point there is now nothing to stop it.
Spontaneous Rotation of a Magnet over a High-Temperature Superconductor
Here I demonstrate an extremely interesting phenomenon. A magnet is suspended by Meissner Effect levitation over a toroid of high-temperature superconducting ceramic cooled in liquid Nitrogen. The ...
