Ohm’s Law for Moving Conductors

Abstract

We are now ready to discuss conductors that move in magnetic fields. An important question comes to mind: do you look at the electric and magnetic fields sitting down with the conductor moving in front of you, or do you ride on the conductor with your measuring instruments? It is important to tell between the two points of view because the fields can be radically different. As a rule it is best to stand still, but not always. Chapters 6, 7, and 8 are fundamental for all the rest of the book.
