Somewhere in my boxes of stuff I've got one of the tape "visualizer" cards.
Its looks like a translucent grey plastic card and when you hold it over a
magnetized surface it shows the magnetic "spots" by turning white (what it
actually does is rotate a flat magnet in the card that is white on one side
and black on the other.) I got this from Edmund Scientific in the mid 70's
I believe. Anyway, some variation on this would work on cores.

Maybe so, but those are practicality issues, not feasibility.
that answer equates to "whatever". Describe the mechanics of displaying
the orientation of a magnetic field in a closed torus? I was trying to
get someone to think on how thjis may be done impractical or not.
I'm not talking about putting leds on the logig arond the cores to show
states.
