Sam if you wander through the maths here : http://sidstation.loudet.org/antenna-theory-en.xhtml you will see that the magnetic induction of the loop is multiplied by the relative permeability Ur of the ferrite. This of course can be large and is why ferrite rods works so well.
How you would fill a loop with the stuff though is hard to imagine. I would think that ferrites are made under lots of heat and pressure. Hence Trevor's speculation that the ferrite is only at the ends and may be a coupling mechanism (or marketing).
