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 k9yc.com/RFI-Ham.pdf and key elements were
added to the ARRL Handbook about six years ago.
