I set up a simple experiment where a dc current carrying bare wire conductor runs parallel with a electrically charged plastic ruler. When no current flows in the wire and the ruler is charged with electrons (by rubbing it with a fur) the conductor will be attracted to the ruler. When dc current flows in the wire , no matter in what direction nothing its changing , the wire still remains attracted to the plastic ruler. When a permanent magnet is approach to the conductor while life the conductor will be attracted or repulsed depending on the current direction (obviously). I thought that the electrons on the ruler will be at half of the speed relative to those moving in the wire , so there will be two electron flows in opposite direction which will lead to a repulsive magnetic force between the ruler and the conductor! What do I'm missing (if I'm missing something)?
