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
