I don’t think that’s true, but I don’t know enough about electricity to refute it. electromagnetism, sure, but as long as the metal loops around it’ll pull in the electricity (I believe).
It mostly does use the outside (a smaller amount can run through the core). But your point is correct–if there’s no insultation between the hanger and the contacts, it’ll conduct electricity.

Electrical engineer reporting for duty!

I beleieve it’s true with high frequency electricity, like in speakers, but not at 60hz
