The only thing remotely like such a force is a vague reference to centrifugal force, which only applies inside a rotating frame of reference. In the part of the video that shows it starting from rest it isn't rotating at first, and therefore centrifugal force is not a factor.
From outside the rotating frame centrifugal force is a consequence of Newton's first law, and is not a real force.

nope , its not centrifugal force bill.
so far we have covered eddy currents , which could in fact
push the ball down providing an assist to the force of gravity.
and we've covered centripetal force and centrifugal force that
have nothing to do with the wheel rotating.
if your not going to use the coriolis effect or the earths
magnetic field then the only thing left is the room , what if
the entire room is spinning around with the camera and the guy
in the video causing the wheel to appear to turn around.
you guys.
