I have done a lot of searching on this in the past and have not found much, it might be simply because I'm not wording it right though.
My question is does any form of directed magnetism exist? As in could I make a magnet that wouldn't attract anything over a foot to the left but would attract something 20 feet in front of me?
The only form of focused magnetism I have seen is a quadrapole magnet, but that isn't quite the same as what I'm talking about. I also saw something on wikipedia.org where the magnets were arranged so that it got about twice the range on one side then the other, but that's it. Sorry I don't have a link, that's just from memory from a while ago.
