- In this video, I explore how the Hall Effect works and why it's incredibly useful. Spoiler alert: the Hall Effect can be used to measure magnetic field. AND, the Hall Effect can be used to measure current! AND, the Hall Effect can embarrass a dead man.
Prepare to get excited.
Professor! ❤ Because of you, I've got an idea about my 12th grade physics which was really really hellish for me without your enthusiastic explanations. Would've really helped if you taught chemistry as well!! But anyways my physics exam went really much better than expected just because of you. Thanks for that buddy!
Wonderful, I learned the basic concepts of Hall Effect here, I have already done the practical of Hall Effect in University, but I didn't get the concept, here I got all the concept of Hall Effect, thank you very much Doc Sir,
A video like this on Fermi energy would really really help Doc. (Saying this with genuine gratitude)
Thank you sir for making this one.
Very well explained. I'm not sure which stage of education this video was made for but helped me in a 2nd-year course in a Computer Engineering university program. Thank you!
Hi , thank you very much
the "pink wire " was the best part in the video 😂
1- no, because , if the conductor is good means n too big means Vh small
2- a- Jole affect
b- I can't be very big because the number of charge is limited
c- I big mean Vh very big also
Thank you for your answers, I can't think of one 😅
By the way, I think you make a spelling mistake. It should be "Joule" instead of "Jole" right?
Wow.. Thank you so much for explaining it so..... clearly
Thanks Doc. Finally got thish
Thanx a ton.doc from the other part of the world- Bangladesh .Ppl often make physics too bookish but u r style of teaching connects us to another world of this invisible electromagnetism...thank u so much
Man I was thinking like I should skip hall effect and then I discovered this video and my life is changes now
You're hilarious :D
And easy to follow.
Is that a joke?
You are hilarious with your badass jokes😂 seriously it was fun
Iwill be so much grateful to you if you will prepare a video on schrodinger equation with full explanation. Thank you
Yes bro I also need
Dr physics
2:55 when you say "by consequence" the negative appear on the botton what moves those negative charge carriers? Is it the magnet or the positive charge carriers?
what is the material made of for example ,when you mentioned thickness of material?
Thanks, an attempt to answer the two questions
1) better conductor will translate to higher number of charge carriers density and thus a lower Vh
Can u please do a video on 3 phase circuits(balanced, unbalanced and wattmeter method) thx in advance I'll be forever grateful
So nice thanks sir
I've two question. 1) How it differs from Lorenz force? Lorenz already had observed for the magnetic field charges deflect. So what new? 2) How -ve charges accumulate for the +ve charges? As we know free electrons move in the conductor. so, we should have accumulated -ve charges across the conductor for the electricity.
Clearly this works because we have Hall Effect sensors, what I’m missing is how there can be a static electric field across the constant potential conductor??
Equasions are fun! 😃👍
Wow, now it makes sense.
Hahaha I love your videos!!
You used Right-hand rule for the positive charge case and left-hand rule to the negative charge case, so obviously, you will get the contradictory results
Would be great if our teacher create a sort of ballance between what he teaches and what he speaks
Whow! thanks!!!!!!
Will you be posting anymore, I really really don't want you to stop :/.
im super confused over the right hand rule here for the positive test chrages and electrons. If you have the electron traveling left, and magnetic field is into the page, and F=qv X B then the force acting on the electrons should be down? pls help XD
It's because the charge on the electron is negative, so the direction of the force you obtain from the right hand rule is reversed: F = q(v X B)
U r awesome
yo Doc, for the next video put some red nail polish on your nails xD
Wait, I dont understand why the force is going upward( in the first example) but the negative charges accumulated at the bottom
I wish I still took physics so I can watch more of your videos! Thanks for helping me get into med school tho
Sir kindly make videos on programming of 8085 and 8086
Sir.. can u teach how to write 8085 assembly level program to design :
When a coin is inserted and when it is valid, port 1 gives code FFH. If it's valid, check whether the request is for tea or coffee at Port 2. 04H code at Port 2 is the request for tea and 40H code at Port 2 is the request for coffee. Open the value for liquid to come out with 04H code for tea and 40H code for coffee at Port 3. These codes at Port 3 are to be used for value operation. When port 4 gives code 00H, value is to be closed with code FFH. Repeat process can start with a new coin. If coin is invalid, 00 indication at Port 5 is to be given and the instruction for inserting a new coin can be given.
Upsc 2010 mains question sir
I don't think anyone is ever prepared for that En Vogue joke.
I'M SPEECHLESS DUDE TEACH ME.
it's funny once I got to that part of the video I was like "NOOOOOO this can't be a prank video this is so informative and intuitive and first principles-itive!!" And I'm like now I gotta double check all the formulas!
But then I'm like damn. I tried to escape the pranksters and they just got SMART AS FUCK.
That was an epic rickroll where's the reggae horn?!
Mad, bcause so speedy.
dude where are the uploads
Still not understanding why tge negative charge is on top
Settle Down Chucky !
Witchcraft and sorcery!
Current ain't vector, doc. I think you don't have to put the right arrow on top of i.
current flows in a certain direction bro, the arrow indicates the direction fyi. :P
This is so frustrating.. Tesla said there is no such thing as an electron. That ends my thinking of moving particles. Einstein was wrong too. Magnetic field migration. Not electron charge carrying B.S.
Get it? Opposing forces are created.
this is not hall effect and done at room temp this is north
Sağolun hocam normalde 10 alıyordum artık 30 alıyorum
olley be tek değilmişim :D
You are too funny
This doesn't explain positive hall voltages though. And that was what I was after.
Please explain more slowly.
current are not a vector so you do not have to put the vector sign in I
Your Hall Bar equation should contain "h" in the denominator, not "w".
You defined the thickness = h and the width = w in your figure earlier, yet your final expression contains the width in the denominator, which is wrong. Every textbook on the topic has the thickness "t"/"d", or in your case "h" in the denominator
I like turtles
You are annoying my friend, you killed my focus
Witchcraft and sorcery!
