Ferrite cores conduct electricity! Ouch! Not brilliantly, but a
measured 10k or so over a cm or so.
I've never been much involved in the black arts of coils, but for the
past half century I've believed/assumed ferrite to be an insulator.
Don't know why.
For some reason, the RM12 cores I'm using have the type printed on one
half of the core only, so mixing up types could happen if you were
careless. I have been. But it seems that the two types I'm using have
quite different resistivities, so I can match up the two halves again.
Cheers
