Till what I know, AC alternates between positive and negative. How does that to make a flow? How do you connect a postivie and negative if it’s always changing?

The physical way to make an AC current is to use DC to power a spinning rotor with electromagnets on the ends, causing the magnetic field to spin. If you recapture that magnetic field back to electricity through a line crossing on one axis only, you end up with a back-and-forth charge in the shape of a sine wave. Your output is AC.
Edit: Modern transformers have pretty rad designs that don’t need moving parts, but I find imagining something mechanical easiest to visualize.
