The strength of the voltage being produced depends on which factors?

The voltage produced by a generator depends on how quickly the magnetic flux linked with the coil changes, and this is controlled by three things: how many turns the coil has, how strong the magnetic field is, and how fast the flux changes as the rotor moves. Faraday’s law tells us EMF is proportional to the number of turns times the rate of change of flux. The flux through the coil increases with a stronger magnetic field, and the rate at which that flux changes grows with faster motion (rotation speed). So increasing the number of turns, increasing the magnetic field strength, or increasing the rotation speed all raise the induced voltage. Because all three factors contribute, the best answer is that all of the above factors are involved.
