How is alternating current produced?

AC alternating current is generated by magnets spining in a generator at 3000 rpm for 50 hz 3600 rpm for 60 hz (1 pair of north south magnets) 1500/1800 for two pairs and so on,

the magnets move the electrons in the wire- copper (since electrons dont like to be neer each other) they move a very tiny amount then back to where they started <<<>>> motion,

in fact the electrons in the power plant never leave the power planet it is just the electrons moveing each other a tiny amount that creates a current.
