AI Thread Summary
Electric flux is independent of the material of the surface it passes through, as described by Gauss's law. While the electric field's magnitude may vary based on the material, the flux calculation involves the dot product of the net electric field and the surface area. The discussion raises questions about whether constants like permeability exist for different materials. Understanding these concepts can be challenging for beginners in electricity. Overall, the key takeaway is that electric flux is determined by the electric field and surface area, not the material itself.

i wonder how come the electric flux doesn't depend on the MATERIAL that the area which the Electric field goes through is made of?>?>>??>

The surface through which the electric field passes through is imaginary, just as what you would expect from Gauss law. The magnitude of the electric field at the surface may depend on the material it is passing through but once you have taken that into account, the flux is simply the dot product of net electric field through that surface.
 
so are there any constants for each material "permeability" of electric field... :)

or u are saying that the general idea is that the E field is always the dot product... regardless the surface.. :) or something like that... i just started studying electricity and I am kinda lost yet :)

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 ...
