   phone has magnetometer, which detect earth mag fields, work as compass. But how's neighbor electric components don't effect it?

      @xahlee If your wire isn't coiled, it takes a lot of current to generate even a small magnetic field. Without doing a careful calculation, I think it's something like an amp that would be needed at 1cm distance, and the actual currents inside a phone are more typically in microamps.
