J.A. Legris said:Just to be perfectly clear, we cannot shield one end of a magnet. The
covered pole just gives a magnet with one end bigger than the other.
In other words, more screws will be attracted to the growing blob of
screws until it's large enough to enclose the other pole and all the
flux in between.
However, the addition of each screw changes the shape of the field. It
will not be always possible to add a new screw at an arbitrary place on
the outside of the growing blob, even when there remain places where it
is possible to add a screw.
