Electrons in electromagnetic induction

Click For Summary
SUMMARY

Electromagnetic induction occurs when a coil rotates in a magnetic field, generating alternating current (AC) at its terminals. The discussion clarifies that electrons do not deplete from the coil wire; instead, they continuously flow in and out as the voltage and current alternate. This process maintains a nearly constant total number of electrons within the coil, ensuring its functionality over time.

PREREQUISITES
  • Understanding of electromagnetic induction principles
  • Familiarity with alternating current (AC) concepts
  • Basic knowledge of electric circuits and electron flow

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.
