The book's logic is that there is no induced EMF because flux is constant as it passes through the magnetic field. Which makes sense, but this seems counter-intuitive to what I previously learned.
If i'm not mistaken, if an electron is relatively moving perpendicular to a magnetic field, it WILL experience a force. The electrons in the ring are moving perpendicularly relative to the stationary field, so why aren't they experiencing a force?

The force on each electron is $qv\times B$, which is toward the left. This clearly doesn't induce them to flow in a circle. (Remember that if electrons flow to the left, current flows to the right.)
The entire ring is not deflected to the right because there is an equal force on the nuclei toward the right.
