Just  how  conductive*IS*  ferrite anyway, i have never probed it.

It depends (a LOT) on the ferrite mix (usually expressed as a type #). Some are good enough conductors to measure with a VOM, others are very good insulators, the rest are "in between." We can learn a LOT from a careful study the Fair-Rite engineering catalog -- I did! You can download it as a pdf from the Fair-Rite website.

A tutorial on some aspects of ferrites (focusing on their use in common mode chokes) is part of and key elements were added to the ARRL Handbook about six years ago.
