For starters, aluminum is the wrong type of metal. Soft iron, as used in
transformers, would be much better. Iron concentrates, or "focuses" in a
sense, the magnetic flux from the coils of wire. What you are trying to
build is really a type of transformer, but with a physical gap between the
primary and secondary windings. The larger the gap, the less power that
will be coupled.

This has been discussed on the list in the past. You might find something
with a search of the archives.
