After this restatement of my orginal post is a summary of the
responses I received.

The responses I received were split between people telling me it could
not be done and others telling me how to do it!  I LOVE the internet :-).

I received lots of suggestions but no pointers to specific literature that
deals with the problem I described.  If anyone has any such material, I 
would still like to know about it.

There were a few responses that described something quite similar to my
contraption but used three or four magnets focused toward a point at which
the metal object was levitated.  Having several magnets makes it possible
to create what is essentially a magnetic bubble or bowl which contains
the object.  

If someone is especially interested in this subject and want some more
detail on the responses I received or better yet would like to help 
figure some of this out - contact me by Email and we can go from there.

Thanks for all the help,
