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

AI Thread Summary
Generators operate based on Faraday's law of electromagnetic induction, which states that a changing magnetic field within a coil induces an electric current. When a magnet rotates near coils of wire, it creates a dynamic magnetic field that influences the electrons in the wire, causing them to move and generate current. Unlike a static magnetic field, which only alters the direction of electrons, a rotating field pushes electrons through the wire, facilitating a flow of electricity. The movement of the magnet effectively accelerates the electrons, leading to a consistent current output. Understanding this principle clarifies how generators convert mechanical energy into electrical energy.

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!
 
Susskind (in The Theoretical Minimum, volume 1, pages 203-205) writes the Lagrangian for the magnetic field as ##L=\frac m 2(\dot x^2+\dot y^2 + \dot z^2)+ \frac e c (\dot x A_x +\dot y A_y +\dot z A_z)## and then calculates ##\dot p_x =ma_x + \frac e c \frac d {dt} A_x=ma_x + \frac e c(\frac {\partial A_x} {\partial x}\dot x + \frac {\partial A_x} {\partial y}\dot y + \frac {\partial A_x} {\partial z}\dot z)##. I have problems with the last step. I might have written ##\frac {dA_x} {dt}...

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
