Does the physical size of the magnet actual come into this?  

My mental picture had a string of MO magnets and two pieces

of bent iron (poles).  This way, you could use as many 

magnets as necessary - the iron or other suitably low
reluctance material bringing the flux back to the desired
point, no matter how long (or tall) the stack.

An alternative would be an iron base with a stack either side with pole
pieces coming from the tops.
