How Does Electromagnetic Radiation Work?

AI Thread Summary
Electromagnetic radiation can be understood through Maxwell's Equations, which provide a complete description of the phenomenon. Despite its seemingly straightforward nature, many individuals, including those with years of study, continue to learn about its complexities. The discussion highlights the ongoing challenges in mastering electromagnetic radiation, suggesting that it is not as simple as it may appear. Participants encourage seeking comprehensive resources, as no single thread can cover all aspects of the topic. Mastery of electromagnetic radiation requires continuous learning and exploration.

i need to know everything about electromagnetic radiation
 
Physics news on Phys.org
there's not much to it. you can get a book and learn it overnight. :rolleyes: all you need are Maxwell's Equations (there are only four of them) and you have a complete description of E&M.

:bugeye:

I've been studying e/m radiation in various contexts for nearly ten years and I am still learning.

RBJ, I hope you're not including QED in this remark.

that and SR to boot.

it's all easy.

Ah, if only I known that when I started.

Gelf, get a book. Even R B-J can't explain everything about E&M in this thread.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

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...
