2 5 Permittivity and Displacement

This video was made for a junior electromagnetics course in electrical engineering at Bucknell University, USA. The video is designed to be used as the out-of-the-classroom component and combined with active learning exercises in class. This video covers the concept of permittivity, or material properties that change the electric field, as well as the electric displacement (or flux) vector, D.

You are God of Field Theory !! Thanks a ton.! Finally understood permittivity after 7 years !!

Learning is a process. Kridnix just came in at the right time for you. It's just a coincidence. No gods to be found here :-)

@@jacobvandijk6525 Please stop trying to push your blind faith down people's throats. We don't know if kridnix is God or not. We all might be God or part of God. We might have fallen down a blackhole & life is a hologram & kridnix is a superb advanced being from the future. Anything is possible

A detailed discussion of polarizability is found in "Dielectric Matter", Ch. 6 of "Modern Electrodynamics" by Andrew Zangwill.

Sir, I really cannot appreciate you enough for teaching. When I took a course in Electromagnetic Field Theory, I hated it SO MUCH with a passion swearing that I will never pursue a career in Telemetry or Telecommunications Engineering. I think you are the very first person to reverse this.

[@bkahraman99]

GREAT VIDEO !!!!!!!!!!!!!!

[@justinle998]

Best explanation on youtube!!

[@mattg1711]

Thank you so much for these videos, you're a very clear teacher. I hope you'll continue to produce more content in the future!

[@yehiaayoub4041]

Absolutely wonderful explanation, got way too confused reading elements of electromagnetics, this surely cleared things out, thank you!

[@HuggumsMcgehee]

This is the first time I've ever understood this property. Subscribe.

[@omega7377]

Magnificent explanation, sir. One of the best explanations in youtube so far :)

[@buraksar5515]

it just fills the gap so perfectly. thank you for your service Sir!

[@Quancept]

The best explanation! Finally understood.

[@Suresh-bx4rz]

Best and most Simple explanation

[@julianjawadahmad1006]

Your explanation is very clear. Thanks a lot!

[@guchiguguchi]

awesome, what a crystal clear explanation!

[@u571lxx]

Great explanation! concise and clear!
For me, I wondered for a long time why those guys created so many terms, e.g. D, P, epsilon... now clearer

you are the best man :D thanks a lot

best tutorial about Field, thanks

[@carlav5285]

Such a great video, thank you!

[@krishvasa7644]

Thanks a lot man!!! This was really really helpful!

[@doc0core]

I have been trying to understand this stuff for 30 years now, I even read Jackson. Finally (rereading Jackson 3e) and your vid helps me truly understand *D* Thank you very much. BTW a tiny typo @14:00 "force" not "force field" has units of energy/distance. Force field has unit of of energy per distance per charge.

[@douglasstrother6584]

A detailed discussion of polarizability is found in "Dielectric Matter", Ch. 6 of "Modern Electrodynamics" by Andrew Zangwill. It's on the level of Jackson, with fewer sharp edges.

[@emanmagdi216]

I like this explanation so much thank you so much

[@manjusrivastava5770]

Excellent explanation 🙏

[@dribblersmy]

thank you!

[@duncandonuts_21]

Is the displacement directed towards the direction of the electric field create by the plates? Or toward the direction of the polarization?

[@tsaigordon440]

splendid speech :>>>

[@odal6770]

You make it sound that there are two electric fields, one coming from outside, and one from inside. But isn't the electrical field itself the result of the electric interaction of one object with another? That therefore always at least two objects need to be present? I know it is often represented as the field created by Q, and that the test charge is somehow brought from the outside to the field. But surely, that is only an abstraction?

[@shudhanshushekharmishra747]

15:20 Phet-C simulation. There's also an app of this. Phil Andersen from Bozeman Science regularly uses it and so should everyone.
