The Hall Effect and Hall emf

[@boluwatifeberida9702]

One will have to stick a rock in his head not to understand this lecture. Wonderful lecture!

[@AKLECTURES]

hah! best comment of the day! thanks! :)

[@tytanty5555]

I guess I have a rock in my head, I need help understanding what this produces and what it can be used for. Please reply so ASAP so I can gain a better understanding on the Hall effect, as I am currently working on a science project, which I believe involves the Hall effect.

[@veerbal1]

Right

[@sergeirachmaninoff6397]

Couldn't agree more. Just by reading the board one could easily understand what's going on.

[@123Handbuch]

Just great, no senseless talking. Thanks

[@AKLECTURES]

123Handbuch thanks for watching! :)

[@arbazkhhhaaqan]

This is by far the most amazing lecture on hall voltage.Thanks a lot

[@saadahmed8580]

talented teachers make wonderful lectures...and one of them is u sir

[@AKLECTURES]

+Saad Ahmed thanks! :)

[@artemis12563]

Can't get a simpler explanation than this on youtube . Thanks professor.

[@NrupeshSurya7]

English is so fluent that the auto captions are matching perfectly

[@jameserayburn]

AK, you do great work young man. Great teaching skills.

[@AKLECTURES]

Thank you!

[@AyushiRai04]

Thank you for making this concept so easy to understand. The way you teach made it very easy to understand. :)

[@mpliew7288]

Thanks for the lecture, you explained to me what and how the hall effect happened easily. Thank you very much!

[@veeds74123]

this is the greatest lecture I've ever watched. I have an exam tomorrow and you explained everything so perfectly! Thank you a million times!

[@AKLECTURES]

Veeds you're welcome! good luck on that exam tomorrow

[@ranapratimsarma9506]

You saved my day. I'm prepared for the viva now.

[@hasanmurattalan8405]

been 8 years and still 1 number 🙌

[@gjohn1000]

You just made the first three weeks of my final year Electromagnetic Field Theory class seem like a walk in the park! Only if I had found this earlier... sigh

[@AKLECTURES]

Gregory John hah i feel your pain :-) well, better late than never. good luck on completing the course.

[@tessie8659]

Thank you so much for so many interesting and tangible explanations of concepts normally difficult to grasp ! I OWE YOU !

[@AKLECTURES]

Tessie You're welcome! :-)

[@vanillaxneko]

Your lectures are great! I was feeling a little too exhausted to be reading through the dense text in my book but needed to understand the material and your video really drove the point home! Thanks so much!

[@AKLECTURES]

Absolutely agree with you!! Textbooks can be very very dense ! Glad to hear it :)

[@abhishektiwari2101]

wow, just wow.. learnt the concept in 8 mins :D

[@CristalPiedra]

It's explicative, yet the Lorentz Force is F=Fe + Fb = q(vxB+E) so the force due to the electric field is the negative of that from the magnetic field (when equilibrium is reached). Also the product Vd B is a cross product. The lecture can be improved by either using vector quantities and vector products correctly, or by reducing the explanation to magnitudes of these quantities.

[@kavidiss7959]

This is really clear. I understood where I have misunderstood. Thank u. Also tip ; playback speed ×1.25 if needed.

[@PhillipeOliv]

The hall effect is so much clear now! thank you very much.

yea i wish i found this earlier too i love how simple and slow but not boring tho keep going in this rate ;)

[@onethkahandawa1909]

Thanks a lot , cleared all my doubts.

[@joelchristopher7669]

Beautiful explanation

[@skatershawn410]

Great explanations, great information... i just wish you would put in some commas and periods between your sentences! Love the info in your videos, it's just hard for me to follow when the whole video sounds like a run one sentence. :/

[@generalc2048]

waw!! This is the best explanation i ever had. Thank you Sir.

[@milenacampos-poz9666]

Love the way you explain!

[@AKLECTURES]

thanks Milena!

[@dimanabdullah8772]

great lecture video it helps me a lot to understand Hall effect.

[@martingalvan6768]

oh lordy god bless your soul

[@ilhamhanapiah2667]

Pure masterpiece sir 👏🏼👏🏼👏🏼

[@karennakye]

You r the best....thx so much for these lectures

[@ashinthaCARBON]

It's really good, i understood everything

[@drps62]

What a cool explanation (lecture); but I wonder, what is the force that makes the electron move over the sheet of the metal initially, and where do the electrons that accumulate on the left-hand side of the metal come from?; (formerly you illustrated a single moving electron) but at the end, you showed many electrons accumulate at the left-hand side of the metal. Could you please explain it from the atomic perspective?.

[@ahmyakm9176]

Excellent explanation👍👍

[@shirazmunir7974]

Excellent lecture..

[@tamarawonglol]

This video helps me a lot! Thank you!

[@AKLECTURES]

Tamara! Thats wonderful to hear! You are welcome! :)

[@nurlisasyahmil7315]

I love this video bcoz I understand what is he talking about.

[@akhilesh317]

excellent..... thanks for uploading

[@AKLECTURES]

Akhilesh akhil you're welcome !

[@davidm3210]

A very nice explanation

[@daanvwb4656]

Sorry to be that person but the Lorentz Force (aka magnetic force) is the CROSS product of qv and B, not the dot product as is shown in this video. The dot product would be zero here since the velocity is perpendicular to the magnetic field. If written as scalars, not vectors, this notation would be correct though. Watch out with vector notations :))

[@mainaksanyal9515]

liked the video and understood too thanks

[@GabiHume98]

Thank you so much for this video!

[@EGOPON]

I think you misrepresent that the vector product. It must be vd x B = E, where "x" stands for vector product. If it was vd*B = E, where "*" stands for dot product; then it will be wrong since dot product of two vectors cannot be a vector but a scalar.

[@yasminelamari4250]

well explained as usual, thank you .

[@yatishsrinivas9104]

excellent video ... i really understood it vry easily.. thank u vry much..!!! wish to get more n more videos on such important topics... :)

[@sifatnashid6873]

man u r just great made it easy for me

[@kega4062]

Amazing video!! Thank you

[@kinshukmajee8083]

great lectures... but would have been better if calculation of mobility of the carriers is also discussed, otherwise great.

[@hirurathnayaka8330]

Thank you so much for this sir.

[@amatoallahouchen5894]

Great lecture, thanks!!!!

[@ArGPaBloSaR]

very well explained! good job and than you!

[@claricea5353]

LOVE UR VIDEOS!!!!!

[@lostcaused]

Great job!!! Thanks

[@syedasabajilani1649]

great video sir

[@tuongngo5896]

Very helpful ! Thank you sir !!!

[@whatisldmdoing]

can we use left hand rule to explain the induced force on the electrons as in index finger pointing out of the board, middle finger pointing to the left and thus the force represented by the thumb points upwards? (referring to the diagram at top right corner)

[@erbazkhan266]

Great video!

[@ughsirius]

Thank you so much for this! You are a life-saver! :')

[@donaalapatt5621]

Thanks a lot sir i understood it very well👨‍🏫👨‍🏫👨‍🏫

[@mscrazy1423]

thanks a lot sir ! really helpful to ace the exam !

[@AKLECTURES]

mscrazy1423 you're welcome!

[@keerthic6925]

Whether the conductivity here increase or decreases?

[@lostcaused]

What's the difference between the Hall effect and the Lorentz force?

[@kshitijshah7950]

Excellent 👍!!

[@alwaysdisputin9930]

2:15 You say "The magnetic force will cause the electrons to travel closer to one side than the other. This will cause" a positive charge to appear on the other side How? are electrons being ripped away leaving a bunch of exposed protons that have a positive charge? is the magnet pushing protons together? are the deflected electrons attracting protons?

[@_DigitalRemake]

Excellent explaination :) subbed.

[@AKLECTURES]

Sachin Anuruddha thanks!! :)

[@ryanyap2807]

its left hand rule for production of mechanical force

[@1996chen]

Great video, thanks a lot

[@bcg7752]

Great job!

[@andyjunior]

Isn’t the electrical field in that diagram in the same direction as the magnetic force?

[@shanakaushan4578]

How to get the hall voltage when a cylindrical conductor is placed perpendicular to the magnetic field?

[@manahilkhan2555]

But the positive charges are also forced to the same side as electrons. How do they get separated? Confused. Someone please help.

[@Captain_Rhodes]

any chance you could explain 1 application of this? could it be used to meaure magnetic field via the point at which current flows or something?

[@TheParhamsabeti]

thanks it helped a lot

[@AKLECTURES]

Perham S you're welcome!

[@aneeshaabdullah4912]

Excellent

[@Barak314159]

and again- brilliant! thank u very much!

[@AKLECTURES]

You're welcome Barak!

[@ayeshakhan3398]

is it important that the metal is made up from conducting material if the metal is non conducting metal than what happen?

[@cet_learning]

Thank you for a great explanation. I'm a slow learner but I got it ! :-)

[@showmik_playmakr]

Thanks a lot.... Really helped me to prepare for my exam at the last moment :)

[@AKLECTURES]

Md. Khairuzzaman Showmik lol best of luck on your exam!

[@MakhanSingh-xe2ip]

Please make a vedio in how hall effect behave on varying the temperature.

[@davidfransch]

Very helpful thanks!

[@AKLECTURES]

Glad to hear it!
