    Hello. I was wondering if there is a difference in the output electricity in different coils with the same magnet that is moving inside them. For example we have a coil composed of a single wire, but very thick, almost as thick as a finger. We have a second one, composed of the same number of turns, same dimensions, only the turns are made with a cable, which is as thick as the wire in the first coil, but this time it is composed of tens of thinner wires. Will the first coil produce more amps instead of volts in comparison to the second one or will there be no difference in the output?
    Also, is there a software that makes simulations of these things? You enter values like type of magnet, dimensions, wire thickness, number of turns and it calculates the output?

    Coils of identical dimensions should generate the same voltage. The current through them will depend on the coil resistance plus the resistance of any connected external load. The coil resistance depends on the conductor length, cross-sectional area and conductivity (neglecting the skin effect which would be an issue only at high frquencies).

    There are simulators of magnetic fields and even solenoids but you're pretty much asking to predict performance of an alternator. Maybe there are simulators but it's very complex to predict alternator performance. For one thing, the air gap between the moving magnet and the core of the coil is critical, as is the core composition and other factors that are hard to model. These contribute to the inductance, which in turn determines the impedance at different frequencies. Not simple. If you force it to be simple, it's no longer useful.
