along (through) the conductor, it gathers up and pushes
electrons before it, as shown in figure 11 (on the following
page).
The area from which electrons are moved becomes positively
charged, while the area into which the electrons are moved
becomes negatively charged. The potential difference between
these two areas is the electromotive force or emf.
c. SelfInductance. Even a perfectly straight length of
conductor has some inductance. As you know, current in a
conductor produces a magnetic field surrounding the conductor.
When the current
