No.

However, bigger wire allows more current without overheating. Thus a generator with bigger wire can produce more current due to having more loops or stonger magnets. The bigger wire itself does not increase the current. It just increases the allowable current.

An "electric generator" is a unit that produces electrcity from a mechanical rotation.
The source of rotation can be anything (i.e. a petrol motor or a turbine in a flow of high pressure fluid.), and has nothing to do with the generator, except that that source "drives" the generator.
The generator itself has two parts: a fixed part (stator) and a rotating part (rotor). The rotor rotates :-) inside a magnetic field generated by the stator.
The faster the rotor turns, the higher the INDUCTION within the rotor, hence the higher the VOLTAGE output (and the frequency if it is an AC generator).
The size of the wires is determined by the maximum CURRENT the generator can produce (in average, 6A per mm^2).
So bigger wires allow for a higher current.
The other part to take in consideration is the heat generated by the current flowing within the wires. This is the Joule effect: the elevation of the temperature in the wire increase to the square of the current.
So, the bigger the wire, the lower the heat.
Engineers calculate a compromise between safety (for the motor), weight (bigger wires = more weight) and required current.

Let's assume the generator's rotational speed is the same in both cases, and the number of wire windings.

The generator has an effective internal resistance. Normally, the external load on the generator has an effective resistance that is much larger. In this case, the current will be nearly the same for both generators.

However, if the external load resistance is exceptionally low, then the generator's internal resistance may have a big effect. In this case, the bigger wire gage will deliver more current. But, remember that the prime mover (motor) driving the generator shaft will have to provide more power along with the extra output current.

The generator produces the current, the wires allow the current to flow to where it is needed to run something. Larger wires have less resistance and will allow more current to flow. If you're looking at two generators that put out the same KW, buy the one with the larger diameter wires.

No. A larger guage wire increases the bandwidth or max capacity of current within the wire but does not actually produce any electricity itself. The generator produces the electricity by converting chemical energy (fuel) into heat (explosion) which drives the motor creating mechanical energy which then spins an electromagnet producing electricity.

Current flow is the movement of electrons or the movement of holes, whichever theory you prefer.

A bigger wire would offer less internal resistance, but I seriously doubt there would be more current just because of the size.

The force needed to move the eletrons/holes would come from a power source. If the power source remained the same, I would think the amt of current would remain the same.

No. Current is independent of wire dia.
But if the current is high then use bigger wire so that it produces less resistance to current and does not heat up or melt!
In short:
Dia of wire depends on current but current is independent of dia

wire does not produce current .in a generator the fuel used is petrol .it starts the generator and is converted into electrical energy.wire allows current to flow thru it.Depending on the resistance value of the wire the current flow thru it varies

in a way yes.. assuming the power output is the same, since p =I R then the bigger the wire the greater the R and since p is constant, I will increase

both can produce the same amount of current but one can flow electrons faster or can tolerate more power than the other. bigger is better.
