one of the best teacher for electrical engineering respected Ankit Goyal sir

[@jyotigarg6466]

After reaching at u nobody require for any institute , thank you so much sir, you really helpful for those students who can't afford the costly courses of high institution

[@ATC_ShubhamK]

28:24 For infinite wire H should be I/(2*pi*r). for semi infinite H will be I/(4*pi*r)

[@EGLMahakal]

(u I/2πr)- magnetic flux density and( i/4πr )- is magnetic field

[@prakharpandey7062]

@@EGLMahakal Please explain more. I am having confusion. When I tried H = I/2Πr.

[@EEEAnkitshukla]

@@EGLMahakal please study once more dear

[@EEEAnkitshukla]

mf density is nothing but product of mu and H

[@adityaupadhyay6932]

if your lectures are going to be in same way as now, we students will surely excel in the gate exam with good ranks.

[@KreatryxEE_EC_IN]

Corrections 1. In Biot-Savart Law while computing Magnetic Field Intensity - Permeability should not be there but permeability is multiplied when we compute Magnetic Flux Density. 2. In Magnetic Field due to infinite wire 2*pi should be present in denominator and not 4*pi

[@eagle5852]

Sir Make Video On B,H And Flux Relation In Biot savart law and magnetism Because I Got Totally Confuse In Many book B is field while in many it is flux density Some use B in flux some uses H in flux

[@prakharpandey7062]

Thank you for the corrections sir.

[@abhineshsingh3353]

What a explanation..... Ankit sir papa of EE

[@debjitbatabyal8858]

i think here should be k= 1/4pi , no permeability should be considered when taking H (magnetic field intensity), B= (permeability)H, check at 8:10

[@Azaharrebel]

R u sure about that 😂

[@dhruvgupta1740]

V= 1885 cos 377 t . Polarity - upside (+) Down (-)

[@grabitgo2724]

At 32:42 the direction of mag. field should be opposite of what is shown!

[@soumyadipsharma3896]

28:21 H should be I/2*pi*r. Perimeter of a circle is 2*pi*r

[@King-qq7iq]

Yes same here

[@mohanraovyandam6492]

respected sir ur teachings are simply superb but we find some difficulties from the language ,,if it is in english it would be awesome sir and if possible please provide the translation subtitles for it where we can relate it to our concepts . please consider my appeal as it will help to may of the students for gate , and iam subscriber of kreatryx and following u daily

[@santanupanja3350]

with due respect sir.. 21:15, where you calculated H. I think there should be no permeability function(Miu or miu not). after that whole calculation in Biot-Savart Law magnitude calculation of magnetic field intensity should be changed, to maintain the difference between B and H. thank you sir..

[@amandeepkumar7855]

bohat acha pdhate hai sir yesa lga jaise real mai class lgg rhi hai very nice

[@kumarrajeevful]

Although I am not a student of Engineering. But I continuously watch your classes. Really your way of teaching is much more appreciable.

[@Bvlog_cricket_ninja]

Sir , H vector ke liye proportionality constant 1/4π hoga ,,,, B vector ke liye u/4π aayega . B=uH ,,,,, thank you sir .

[@alakhniranjan6602]

Yes

[@ankitkrsingh-sp3kl]

yes bosss... u r right

[@ankitkrsingh-sp3kl]

I think we should assume that sir has misprinted B by H. after that every thing will be ok.. (replace H by B only in the discussion of Biot savart law ) otherwise make some changes in formula taking only 1/4pi

Sir Permeability should be multiplied with enclosed current in ampere's law

[@javedalam103]

Bhot he umdah content ❤❤

[@arjunpareek1877]

H due to infinite long current carrying wire is H=I/2*pi*r and H is independent of permeability so its expression will not contain it.

[@priyapandit6263]

I m very greatful..

[@AbhishekThakur-vr4zy]

Awesome videos sir But ek major concept mistake jo batai hai ki lenzs law me aapne likhaya it opposes external magnetic flux but actually it opposes change in external magnetic flux baaki mistakes toh chal jayengi

[@divyaagrawal5093]

Sir u hv marked the wrong direction of current after first loop in solenoid...after correction H will be in right to left direction.

sir at time:53:01, which is used in ndfieby dt.....if external flux and induced flux are same then both can cancel each other.....

Sorry sir but I think field due to infinite current carrying conductor should be H=µ0 I/2πr

right ,it mistake 😊

[@adityaraj8518]

If u get time apart from this then make a vdo on only opam for gate EE

sir magnetic field intensity does not depends upon medium , so i think you shoundnt take K as mu 0 .mur / 4.pi...please explain it ...i think k will be only 1/4.pi..when we find B then mu o and mu r comes into picture
