As some will know I've been messing with drum cores.
How do I work out approximately the magnetic path length for a drum core, I need to work out an approximate saturation flux level for my particular core (I only have al factor and bsat parameters nothing else).
Do I assume that the core has enclosed sides or is the path length 2 x each 'C' section.
(the former looks like a cotton reel having 2 'C's back to back cross sectional view).
I dont know permeability so I'm not able just to stick on 10 turns make some electrical measurements and calculate path length.
