I work for an electric utility company and part of our job is to locate underground electric utility cables. Of course there is high tech equipment to accomplish this, but a few weeks ago an old lineman showed me a trick using two pieces of #6 copper wire bent at a 90deg angle. He would hold these loosely in his hands and walk slowly across the road, when he would get over the buried line they would cross. We then put the locator on the cable and it confirmed its location, he was right on. I then tried this method and it seemed to work for me too. I have done it on multiple occasions since then and it always seems to work.
This reminds me of dousing, and I am cannot think of any realistic mechinism by which this could work. The most likely explanation is that since I have a pretty good idea where the cable is to begin with I could be subconsciously moving the wire myself. Or could it have something to do with the changing magnetic field that surrounds any cable energized with alternating current, could this be acting like the iron core in a transformer and be conducting the magnetic field? This seems less likely due to the distance that the dousing rods are from the conductor.
Does anyone have any thoughts on this?
