If you weren't too stubborn you could find many, many online references
to the dielectric characteristics of ferrites. A ferite core absolutely
IS a dielectric. There is nothing false about what I've been telling you.

Now then, whether you want to acknowledge it or not, a ferrite core
IS a lossy dielectric and can get hot when you put a high enough RF
voltage across it INDEPENDENT OF THE CURRENT FLOWING THROUGH THE

dielectric losses of ferrite materials if you just bother to do some
internet searching. This is NOT an insulation breakdown issue ...
not at all.
A dielectric is defined as an insulator . A ferrite core is not a
dielectric (insulator), This is the false fact in your theory.
*Dielectric heating*, also known as*electronic heating*,*radio
frequency heating*, and*high-frequency heating*, is the process in

It is the dielectric material being heated via molecular rotation.
A ferrite core although not a good conductor also is not a dielectric,
and no mention of dielectric loss is attributed to its heating losses ;
