The shifted electrons exert an electrostatic pull on the positive wire lattice, thus creating the attraction between the wires.cabraham said:Sure. But does that change anything? With 2 currents in the same direction, the electrons shift inward creating a repulsive force between the 2 wires. But we observe that the force is attractive. How?
The electrostatic force on the electrons is equal to the magnetic force.Answer - there are both electric and magnetic components of force. The mag is much stronger. In machines class this was repeated often. What you're saying is not what is being disputed. What lies at the heart of this is that the H field attraction exists in addition to the E field attraction. Both are present, but the force due to H is stronger than that due to E.
