I was playing around with an app on my iPhone that included a Magnetometer. Interesting that when I took measurements over the Shunyata power cord, it actually measures no more than the ambient room reading of 42.77 uT. Reading the other power cords I have at hand is almost double at 74 uT when driving the same component. Even the interconnects in that same component, in this case the Bryston BHA-1, read much higher at 61uT.
