Hi Meredith,

       Sorry, but I don't understand Brett's suggestion. You would get the 
best results by adding end plates and a central core. One end would be a flat 
plate with the circular central core mounted on it. The other end would be an 
outer ring at the end of the magnets and a gap to the central core. This would 
concentrate all the magnetic flux in the circular gap between the central core 
and the end ring. The end ring collects most of the flux and concentrates this 
over the ring gap. The magnetic saturation of iron is about 1.6 x that which 
is produced by Neo magnets.   

       Regards,

       Chris
