Steel balls on rotor instead if magnets | Sticky Point

I have come across this idea on net.
Why not use steel balls on rotor instead of magnets?

Steel balls do not get attracted to the shielding material and that will avoid the sticky point. Will this work? The attraction or repulsion will be less compare to a magnetic rotor but atleast it has a chance of passing the sticky point.

What are your thoughts? Am I missing something that I cannot find a reason why steel balls would not work if it would not?

The problem is that steel balls get magnetized when approaching another magnet. And it will be magnetized in the direction of the magnetic field from a magnet. This will cause the steel ball to fibd a sticky spot ehere the magneyic field is strongest. Basically.

So if the magnetic field is strongest over the hole in the track, are you saying the ball will hang in the air? Or are you saying the ball will know to stop before the hole, so it will not drop through it?
