Current Carrying Wires--No force b/t them? Faraday's law predicts that two current-carrying wires, when placed parallel to each other, will exert an attractive force on each other. Conversely, two wires that are placed anti-parallel to each other will exert a repulsive force on each other. While I was vacuuming my apartment today, I decided to test this phenomenon. I folded the wire into two parts such that one part of the wire was touching the other, with its current flowing in the opposite direction. The result? Nothing. According to Faraday's law, however, the wires should have exerted an attractive force on each other. I then folded the wires such that one part was touching the other, with its current flowing in the same direction. The result? Again, nothing. But according to Faraday's law, the wires should have exerted a repulsive force on each other. How can I make sense of this result? Of course, the electrical input is AC 60hz, not DC. But this shouldn't matter. If the wires are parallel to each other, then on the positive half cycle, both currents will be in the same direction, and the wires will exert a repulsive force on each other. Likewise when the input is on its negative half cycle. The frequency of the input would not seem to make any difference. Maybe the rubber coating around the wire stifles the magnetic field created by the current flow? I've never read anything that would suggest this. Any comments would be greatly appreciated.
