CasualKilla Posted March 24, 2015 Author Share Posted March 24, 2015 (edited) It should cancel, but the only way to produce that field is to run a canceling current down the wire, so that's really the trivial solution. What is a wire carry the the same AC current is the opposite direction why placed next to it. Lets assume very very thin wires.

swansont Posted March 24, 2015 Share Posted March 24, 2015 What is a wire carry the the same AC current is the opposite direction why placed next to it. Lets assume very very thin wires. In the far-field limit, there will be no magnetic field. Close to the wires there will be, i.e. when the distance is not small compared to the wire size and separation. This is the very reason you use twisted pair or coaxial wiring. Link to comment Share on other sites More sharing options...
