Electromagnet Design Questions

Hello !,
I am trying to design one of those magnetic levitators that use a
solenoid to hover a metallic ball. It's mainly going to be used to
demonstrate transfer functions and types of control.
Anyways, I am looking for some basic tips on how to create an
electromagnet to be useful over a longer range. I am hoping to have the
ball hover at least 2 inches away from the surface of the
electromagnet. What would the tradeoff be between a flat or long
electromagnet?
I am not worried about the electrical part of the design, since that is
my specialty. But, I don't really have an in-depth understanding of how
the electromagnet works and how you can focus the flux lines.
Also, is it worth trying to find another material for the core other
than iron? Any suggestions? Suppliers?
Thanks a lot!!!,
Steve
