Where to find Electric displacement help

AI Thread Summary
Electric displacement fields (D) differ from electric fields (E) primarily in how they interact with charges, specifically that D lines terminate at free charges while E lines terminate at all charges. The discussion seeks online lectures or textbooks that clarify this concept, particularly in relation to Griffiths' explanations, which are deemed insufficient. There is a noted challenge in grasping the intuition behind electric displacement compared to previous electromagnetism concepts. Participants are encouraged to share resources or explanations that simplify the understanding of D fields. Overall, the focus is on finding effective educational materials to bridge the knowledge gap in this area.

I'm having a little trouble wrapping my head around the idea of electric displacement fields, it doesn't fit in with any the intuition I gained from lower devision E&M. Are there any lectures online dealing with the subject? Or textbooks that do a particularly good job of explaining? (My class uses Griffiths, who I'm usually pretty happy with, but his explanation of the topic isn't sufficient this time).

To clarify: my issue is with the difference between electric displacement (D), and the closest analogy I know, electric field, in an electrostatic environment. Things like how E field lines end at any charge and D lines only end at free charges. If you want to explain it yourself that would be helpful as well, but since I have a weak understanding I cannot form pointed questions that can be answered easily.
 
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...
It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
