With respect, I don't believe this to be correct. A ferrite/dust iron cored
inductor has exactly the same basic characteristics as an air cored inductor.
It has inductance, loss resistance and distributed capacitance. For a choke
(which is another word for a particular use of an inductor) to appear (almost)
purely resistive it must be operated as part of a resonant circuit, or be such
a poor inductor that the loss resistance is predominant!
