You know how there are those commercials about how anyone can help a foster child but not everyone can be a foster parent.... The same applies to college professors. Thank you great teachers on TH-cam.
Just a note, some people may not understand vector hence not understanding dot-product. With dot-product just multiply the cos θ into the two being dot-product and replace the dot-product sign with a multiplication sign. In this case θ is the angle between the two vectors or the angle between the Magnetic field and dL. So θ is zero because the angle between the two vectors is zero hence cos 0° is one.
He added one additional term called the "displacement current". Until then, Ampere's law allowed someone to calculate the magnetic field due to a current. This additional term, displacement current, accounted for the fact that magnetic fields can also be caused by changing electric fields. By adding this term, Ampere's law became much more similar to Faraday's law and also allowed Maxwell to explain electromagnetic waves.
I appreciate the clarity of his explanations, I find it useful for situations where you wanna second guess yourself about fundamental concepts. I'm enjoying your catalogue of videos. Dare I say this, they're fun to watch.
thank you so much! i love your comparisons between the different laws. ur comparison between LC circuits and mechanical oscillations were also a great help. thanks so much for making these videos
I signed in just to tell you that you are an amazing prof ! :D It is just a great video and it helped me a lot .. my prof doesn't help me much so THANK YOU MAN !! BLESS YOU
Much worse for foreigner students like me to understand or learn engineering subjects in a foreign language. Start to regret my decision. But thank you, teachers on TH-cam.
So were you in electrical engineering which university, man. I have this concept in our senior year. The entire physics 1 textbook has eight chapters on electricity and magnetism.
I understand that, but dl has to be non-zero in the first place before we can take its dot product... Sorry for the confusion. Thanks for the great videos and your prompt reply, btw! :)
I can't stand those high pitch sounds your marker does when you press it too hard on the paper. It's really annoying for me ( maybe use a low pass filter for the sound). Good video tho !
Good explanation of the math. But what's a field if it's a vacuum, i.e., nothing? So we've explained it how? Yes, I know - the most dreaded question in modern physics; what's a field.
you know physics and i don't but what i know that you don't know is you know it more than you think you know it. now get us know it the way you know it and quickly....please.
I don't think that we know that he knows what he knows more than he knows that we could know that he knows it more than he thinks he knows what is known to everyone that knows what's known.
This man is a symbol of clarity and straightforwardness
You know how there are those commercials about how anyone can help a foster child but not everyone can be a foster parent....
The same applies to college professors. Thank you great teachers on TH-cam.
The way you compared the two fields, electric and magnetic made a lot of sense. Thank you so much.
2:52 you got me
THATS A NECK BOY

Oh god finally an easy, straight forward explanation!
The best explanation I have ever had
u r doing great job

At no point in this video do i have any clue as to whats going on, however i watched this video two times in a row and i love it...
This 10 minute video >> two hours of lecturing by UW professors. Thank you!
I hope you are a physics professor because students would be so lucky to have you
I am quietly optimistic about my chances in my Physics test tomorrow, thanks to you.
the table of the two laws makes it soo much clearer! thank you!

Here 12 yrs later, bless you🙏🏾
He's the hero we need but not the one we deserve
why the hell cant my engineering instructors teach like you...angry college student here
I know right
well, guess im glad to see that nothing has changed in almost a decade!
Much worse for foreigner students like me to understand or learn engineering subjects in a foreign language.
Start to regret my decision.
But thank you, teachers on TH-cam.
So were you in electrical engineering which university, man. I have this concept in our senior year. The entire physics 1 textbook has eight chapters on electricity and magnetism.
sir did we have to also include the current on the amperian loop in the "I" on left hand side????
You sir, are an expert. Thank you very much.
You sir have a talent 🙌
Because when you take the dot product the vectors turns into just the magnitudes of the vectors.
Thq 😉
You're so much better than my professor at teaching this :)
I understand that, but dl has to be non-zero in the first place before we can take its dot product...
Sorry for the confusion.
Thanks for the great videos and your prompt reply, btw! :)
I needed a good refresher for this. Thank you!
This video was extremely helpful! Thank you very much!
do you have an intutive argument for why a current carrying wire NOT enclosed in the loop
does not contribute to the line integral of B dot dl
dl is always pointing in the same direction as B? i dont understand
congratulations, you are a great teacher
You are seriously amazing. I love you !!
Haa!! First time somebody towered above my Professor. Thanks mate.
thns 4 uploading,combination with gauss;s law is very helpfull to understand amperes law
Really helpful, thanks a lot.
Thank you very much for your clear explanation of both concepts!
gauss's law can be used for any type of situtation even if it is not symmetric,till its a closed surface !
Why aren't the dl vectors zero, since they end where they start (closed loop)?
You're awesome! This videos are really helpful. Greetings from Poland.
any advice for how to study for engineering courses?
Not sure how i go about applying this to a rectangle with magnetic fields coming out of it at a random angles xd
Thank you! You are awesome, sir!
this video lecture is precious
Very nice, clear explanation. Thanks.
Yo it’s been 11 years, I’m just wondering how have you been? Are u still alive? Lol
so professional god bless you .
Gauss's law is double integral for a closed surface. 0:20 , its a single integral. It has to be double, since you're working with a Gauss Surface :)
double integral of what? 5 years later
OMG!!! You are the GOD!!!
Hey! Thanks for the video. It was really helpful! I just want to ask why is dA=4*pi*r^2 for Gauss Law and for Ampere's Law is dA=2*pi*r? Thanks.
+Ira Shvydchenko Thank you very much!! :)))
you're welcome
did he just draw a pokeball? oh, its just a gaussian surface xxx
It's definitely a pokeball
Let's try to catch bulbazor 😍
You helped a lot. Thank you.
thanks for providing a good video .... this was really helpful !!!👍👍👍
Superb lecture sir
you rock you are simply awesome true respect man....
I bet being a professor for an E&M class must be entertaining during magnetism exams.. hundreds of students using Right Hand Rule..
Very helpful! Thank you so much!
😭if only my physics teacher was as good as you at teaching
im acing my test tomorrow Thank you
This is fantastic! Thank you.
you are a god damn legend sir.
Great video
nice lecture
where is part 2
Awesome sir
merci pour toutes les video d'électrostatique
oui
very clear and neat.
thank you
thanks for great videos :)
this was very helpful. thank you
great video ..
I can't stand those high pitch sounds your marker does when you press it too hard on the paper. It's really annoying for me ( maybe use a low pass filter for the sound). Good video tho !
thanks you very much for that lecture
Thanks, very helpful, keep posting :)
Great job, thanks!

Right..... magic. If you say so.
we need to discuss the displacement "current" dD/dt ... without that we are missing something.
Agreed. That comes later in the course.
Excellent!!!!!!!!!!!!!
Bless your soul
you are the best!
Thank youuuu very much 🌹
nicest explanation , thanks man
helpful video
you know physics and i don't but what i know that you don't know is you know it more than you think you know it. now get us know it the way you know it and quickly....please.
they don't think it be like it is but it do
I don't think that we know that he knows what he knows more than he knows that we could know that he knows it more than he thinks he knows what is known to everyone that knows what's known.
Thank you
:* for helping me out.
Thank you!

Thankyou.
Am I the only 12th grade student studying something from college level 😅😅
This problem was pretty involved.
Thanks!
Perfect
Lol this was posted exactly two years ago
XximmortalimagexX liked this so here i am
cheers dude.
merci
I LOVE YOU THANKYOU
Awesome
THANKS A LOT MAN
just remove all the spaces you can also find part two in his vedio list
great!!
2:52 Got eee'm coach
I saw that too xD
handring XD
