What is the Sign of Induced Voltage in Each Rotor Segment?

[BlackMelon]

Homework Statement

I want to know the minus/plus sign of induced voltage of each rotor segment. Like in file no.3, equation 4-19, why (vxB)•l is not equal to e_ab instead?

Homework Equations

equation 4-19 and 1-45

The Attempt at a Solution

I was searching on this book, but found nothing.[/B]

Thank You

Can you type this out? Your pictures are hard to see.

Thread closed. @BlackMelon, I agree with the previous poster that the images are too unclear to read. Please start a new thread, with equation 4-19 typed out.
