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 KZread.

THATS A NECK BOY

The way you compared the two fields, electric and magnetic made a lot of sense. Thank you so much.

Oh god finally an easy, straight forward explanation!

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.

u r doing great job

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.

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.

The best explanation I have ever had

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

the table of the two laws makes it soo much clearer! thank you!

I am quietly optimistic about my chances in my Physics test tomorrow, thanks to you.

I hope you are a physics professor because students would be so lucky to have you

I needed a good refresher for this. Thank you!

This video was extremely helpful! Thank you very much!

Here 12 yrs later, bless you🙏🏾

Thank you very much for your clear explanation of both concepts!

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 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

You're awesome! This videos are really helpful. Greetings from Poland.

You sir have a talent 🙌

Really helpful, thanks a lot.

congratulations, you are a great teacher

You're so much better than my professor at teaching this :)

You are seriously amazing. I love you !!

why the hell cant my engineering instructors teach like you...angry college student here

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 KZread.

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.

You helped a lot. Thank you.

Thank you! You are awesome, sir!

This is fantastic! Thank you.

sir did we have to also include the current on the amperian loop in the "I" on left hand side????

thanks for providing a good video .... this was really helpful !!!👍👍👍

so professional god bless you .

Very helpful! Thank you so much!

Haa!! First time somebody towered above my Professor. Thanks mate.

you rock you are simply awesome true respect man....

this video lecture is precious

thns 4 uploading,combination with gauss;s law is very helpfull to understand amperes law

this was very helpful. thank you

very clear and neat. thank you

Because when you take the dot product the vectors turns into just the magnitudes of the vectors.

Superb lecture sir

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! :)

Very nice, clear explanation. Thanks.

Thanks, very helpful, keep posting :)

great video ..

He's the hero we need but not the one we deserve

you are the best!

thanks for great videos :)

thanks you very much for that lecture

Thank you!

Excellent!!!!!!!!!!!!!

OMG!!! You are the GOD!!!

gauss's law can be used for any type of situtation even if it is not symmetric,till its a closed surface !

any advice for how to study for engineering courses?

nice lecture

Not sure how i go about applying this to a rectangle with magnetic fields coming out of it at a random angles xd

you are a god damn legend sir.

Thank youuuu very much 🌹

Thank you

did he just draw a pokeball? oh, its just a gaussian surface xxx

Let's try to catch bulbazor 😍

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

:* for helping me out.

dl is always pointing in the same direction as B? i dont understand

Thanks!

Perfect

helpful video

thank you

Thankyou.

great!!

Why aren't the dl vectors zero, since they end where they start (closed loop)?

THANKS A LOT MAN

I LOVE YOU THANKYOU

im acing my test tomorrow Thank you

Awesome

cheers dude.

GREAT

😭if only my physics teacher was as good as you at teaching

merci

I bet being a professor for an E&M class must be entertaining during magnetism exams.. hundreds of students using Right Hand Rule..

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 :)

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.

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.

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.

we need to discuss the displacement "current" dD/dt ... without that we are missing something.

This problem was pretty involved.

B (dot product) dL = B *dL*cos(0) Cos(0)=1
