Talk:Proximity effect (electromagnetism)

Ampere force

Is the Ampere force also a cause of current crowding in wires? This is the force between DC currents that causes two wires carrying DC current to be attracted to one another. I would think this would also affect the current distribution in two parallel wires. The magnetic field of one wire exerts a sideways Lorentz force on the electrons in the other wire $F=q\mathbf {v} \times \mathbf {B}$ which is toward the other wire. This should cause the electrons to crowd toward the side of the wire adjacent to the neighboring wire, the same as proximity effect. Perhaps the article should distinguish between these two effects. --Chetvorno^TALK 22:09, 4 May 2017 (UTC)
