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 'Inducing EMF Through a Coil: Understanding Flux'

Thread 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

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 ...
