How exactly do generators work (Please explain the Faraday's law)

Click For Summary
SUMMARY

The discussion centers on the mechanics of generators and the application of Faraday's law. It is established that a rotating magnetic field induces an electric current in coils by influencing the movement of electrons. Unlike a static magnetic field, which only alters the direction of electrons, a rotating magnetic field effectively pushes electrons through the wire, resulting in a flow of current. This principle is fundamental to understanding how generators operate.

Hi, everybody!

I have done tons of research through the Internet, but still can't understand the Faraday's law and how a generator works.

I understand, that inside coils, placed into a rotating magnet, current is generated. But why? What exactly happens to electrons, so they form current? As I read, a static magnetic field influences on electrons only in such way that it changes their direction, but it isn't enough to make current. Why that is a rotating magnetic field, that creates current? How it impacts electrons in comparison to a constant magnetic field?

Will it be right, if I say, that in a rotating magnetic field electrons change their directions asymmetrically - so some electrons approach to other and repel them, thus accelerating their flow?

Welcome to PF!

It really is no more complicated than that because the electrons are charged, moving a magnet past them in a wire pushes them through the wire.
 
Thanks!
