a force, \(F_{gB}\) is created that lifts the disc towards the vertical axis. The vertical component of \(F_{gB}\) acts against gravity and is the force that keeps the spinning disc from toppling over. The horizontal component of \(F_{gB}\) is the centripetal force that spins the disc about the verticle axis. An anti gravity-stunt. This precession anti-clockwise was due to a tendency to drop under gravity in the first place (post "Precession Under Zero Gravity").
When the disc is made to precess in a clockwise direction, ie a velocity component into the paper as shown below,
a force \(F_{gB}\) develops that causes the disc to drop further away from the vertical axis.
In both cases,
\(F_{gB}=\pi v\times g_{B}\) per unit mass.
This force is a due to \(g_{B}\), the \(B\) field analogue of gravity and velocity \(v\), transversing \(g_{B}\).
When the disc is spinning vertically, its axis in the horizontal position, and made to precess in the anti-clockwise direction, we may have an anti-gravity device,
