Where would most of the magnetic flux be in an air cored solenoid close wound using insulated iron wire, or in a partially stretched slinky ? what would the field look like?
A quick google produced nothing but I'm sure I read something in the past, I'm off to do more searching but I thought that this may be a nice mental puzzle hence this post. If you already know ... what is the answer ?

Generally speaking I can imagine field shapes; bar magnets, short or long solenoids, transformer air-gaps etc If the wire was copper then I'd just treat it as a solenoidal winding, if the iron wire is laid along the air cored flux lines then I can imagine it, or even as an iron helix inside OR outside of the winding, but when the winding wire itself is iron ?
