Here is a a PDF file "Magnet force shield attraction 11-8-18"

I am building a cross slide module for my test bed.  This magnet orientation / set up uses
pole to pole orientations for the fixed and sliding magnets and a "polar checker board"
configuration for the shield magnet array.   The shield is very effective and output
forces are around 4 times greater than in previous videos.

would be interesting to know the magnitude of the force of the inserting and removing the sliding shield.

What is interesting is not only the magnitude of the force, but the work of the force, i. e. the energy.
Force alone is misleading. For example, the force exerted on a magnet sliding away parallel to another magnet is less than the force exerted when the magnets separate perpendicularly. Nevertheless the work is the same.

I think the other way around, perpendicular separation produces almost no effort.

To determine the work / energy expended in simple magnet interactions...
