Magnetic wheel by steel shielding

[Floor]

In these orientations there is a good neutralization / net balance of forces, but only
within a certain band of distance between the two magnet sets.

[Floor]

In these magnet orientation, illustrated in 1-2-4, 1-2-5, 1-2-6 jpg illustrations (below),
the N and S poles of magnet #1 are in a near proximity to one another.
The 2 poles / the field is / are majorly / immediately interactive....

as compared to the distance between the N and S poles of magnet
1 and magnet 2 in the 1-2-3 jpg illustration (above).

The distance between the poles has an effect upon the overall interactions / forces,

In drawing 1-2-4, the magnet (#1) is very soon, self shunting between its own poles. 
At a certain point, its own poles are nearer to one another than they are to the pole on
magnet #2.

Also....  in the configuration illustrates in drawing 1-2-4, forces are neutralized in 2 planes
of motion.
