[QUOTE="chrisc, post: 1086321, member: 746"] Yes it is, I know that The size of a magnetic field generated by an AC current (not voltage) in a cable diminishes by the square of the distance from the cable. It is a scalar quantity The magnetic field density can be calculated using B-u*(NI/I) but would really only apply with much larger currents. (u = magnetic permeability of air) Lets assume that the current through speaker cables is 5 amps. The subsequent magnetic field will be so weak that any voltage in the adjacent spaced cable would not be measurable by consumer instruments and be overwhelmed by the signal (music in our instance) You can also read this text: http://www.phys.uri.edu/~gerhard/PHY204/tsl216.pdf [/QUOTE]
