Weber induction force and EMF

AI Thread Summary
The discussion centers on the behavior of free electrons in a transformer's primary coil when a voltage is applied. Participants explore whether a photon flux enters the coil and how this affects electron movement and the coil's electromagnetic field until a steady state is reached. The conversation also touches on the Drude model and its relevance to understanding electron dynamics in conductive materials. There is an emphasis on the need for clarity in physics concepts, particularly in relation to Maxwell's equations and their application in high-frequency technologies. Overall, the thread highlights the complexities of electromagnetic theory and its practical implications in electronics.

We know that primary of a transformer is a coil(mono or multilayer) from a conductive material, usually copper, which have a proper lattice.Inside the lattice is a cloud of free electrons .When in circuit, a voltage is applied at the coil heads.

1.When voltage is applied , do we have a corresponding photons flux which enter in through coils section wire and guided through copper internal lattice to other head of wire.?

2.Suppose a free electron is at an arbitrary position in coil wire.Which will be it's movement and changes in characteristic values in an coordinate system attached to coil, follow to moment of voltage application, until we can talk about a current of electrons in wire? How the linkage field of coil evolve for moment of voltage application until steady state ?.

Welcome to the PF. :smile:

I see from your Profile page that you have a Masters degree and are working on your PhD. What is your field of study?

Are you familiar with the Drude model? At what level have you leaned Maxwell's Equations so far?

I have a master in electronics including radio - computer science .Also studied Math-Informatics. Phd Theme is adaptive phased array antenna .But I need to clear with some physics concepts before that(just for myself)I Maxwell equation ,yes.I am ok with many chapter of maths but sloopy with time evolution of experiments and concepts in Physics.I try to have an order with these.There are many concepts in courses without author's names and the generated experiment specification.
I look some papers with Drude model, we study it at very high frequencies technology course, but no mention about "Drude model".And I think that there are more models from beginning of 20 century exposed but no mention about authors.I will follow the line Drude–Lorentz model, Drude-Sommerfeld model and extensions,Hartree-Fock,Kubo,Fermi ,plasmons model ;Thanks !

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
