Maybe I just don't understand, but the square magnet doesn't move. I can make the magnet affect a square area that corrsponds to the size of the landing craft, but when I move the landing craft, and the magnet with it, the magnet only affects the square area I originally created. The square depression does not move with the landing craft. I can get a depression to move with the landing craft, but that depression is circular, and doesn't do the trick.
