Hello, when a coil rotates in a magnetic field an AC is produced at the ends of the coil but do that electrons come from the coil wire ?
If yes, shouldn't the coil run out of electrons after some time ?

thank you

If you want to use that AC, you always connect both ends. Electrons flow in at one end and exit at the other, and back again when voltage and current change their sign. The total number of electrons is always (nearly) constant.
