And the voltage. The voltage induced per turn is flux - magnetic field strength and rate at which you cut the lines. So speed and magnet strength directly...

Yes. You get an amount based on field strength and rate and that amount is then multiplied by the number of turns. In the real world the flux will have a bit...
