Selection of proper wire for Ferrite core

How much current do you plan on passing through the wire?

Here's a link to a table of wire sizes and resistances:

It's a handy one because in addition to AWG size, diameter, Ohms, and Amperes, it also has frequency limits for 100% skin depth on solid conductors.

You might want to read through this page:
It's for low-current high-voltage flyback converters, but there's some good info on using ferrites in winding transformers/inductors for power supplies, and testing them.
