Lov'n the MC-0.5's but - a magnetic question


I'm totally on-board with High Fidelity's MC5's. You can't argue the improvement just 2 make in a system and it's somewhat confusing how additional ones work so well with apparently no diminishing return. In a short 4 week time period, I've added 6 (in increments of 2) to my preamp line and am ordering 6 more today for my amps.

I have one nagging question about regarding how well they work. After reading a review about their cable construction, there is mention that the core wire of each interconnect can't be silver, copper, or gold due to the fact that these metals won't conduct magnetism. I realize this truth. How then, is the MC-0.5 advantageous to a power line since the magnetism should not be able to flow through the system? 

It may be one of those "If I tell you I'd have to kill you" questions.

Understanding that magnets improve or focus the flow of electrons would seem to be dependant on how far downstream they are. However, I might just be overthinking this. 
tgun5, you ask a good question. I'm not sure what kind of answers you will get? You can always ask HFC that question and if you do please post the answer.
The current flowing through any conductor produces magnetic fields. It's the right hand rule.☝️
