Wikipedia (https://en.m.wikipedia.org/wiki/Homopolar_generator) says a Faraday Disk works by a magnetic force that pulls electrons to the center of the disk, creating a potential difference (negative on the center and positive away from it).

However, if the magnetic force is perpendicular to the electron's motion (which is circular), wouldn't it generate a centripetal acceleration on the electron? How can it "pull" the electron from its circle of motion? How is it doing work if it is perpendicular to displacement?

You have to look at the driver / driven factors. This is a generator where power is coming from the rotating disk and follow your FBI rules. F is rotation of disk and b is cutting through the face of the disk. The current is then either going to be towards the center of the disk or the outside of it depending on the orientation of the other two.

The speed of electrons is mostly due to their rotation. Drift velocity of electrons is actually negligible.

I think what you are missing is that the only electron flow is through the wire and an imaginary strait line from the origin to the brush on the exterior of the disk.
Without the conduction path, there is no electron flow whatsoever, let alone some kind of circular electron flow you are imagining.
There is no magnetic force pulling electrons to the center of the disk. There is a potential difference between the center and the edge of the disk, when it is rotated through a magnetic field.

Think of the disk as an infinite collection of infinitesimal single wires that are being passed through a magnetic field, and it should make more sense.

These are always the go-to for violating a variety of undergrad physical rules that MBAs latch onto in my field. Filter desu.
