XII 50 EMI Motional emf

[@orophilic-13]

Sir I am from Pakistan ....I got a lot about physics from you're lectures.. Thanku sir

[@pawanpanjwani7373]

sir how lenzs law is in accordance with conservation of energy

[@pawanpanjwani7373]

sir why resistors wires etc do not generate back emf why only inductors and capacitors

[@tahirnawaz1234]

Sir how EMF is induced in the conductor in unoform magnetic field?

[@ANMOL355]

Sir please reply I am really confused. I have checked 2 books & in both of them and in your lecture also you took North pole of the magnet to be the interacting pole. My question is that if I use South pole the for interaction, then the conventions be same or different? For example we got anticlockwise direction of current to act as a north pole and clockwise to act as South pole. So if I use South pole of my bar magnet as the interacting pole then, will I get south pole on clockwise direction of flow of current and north pole on the anticlockwise flow of current??????? I know it's confusing. :P

[@kunibaki]

really very helpful . you are building my confidence . thank you so much sir

[@faridakhan3418]

I always used to skip d topic whenever emf comes... thnkyu sir for clearing d concepts 😊

[@niharshah079]

Sir in the example of the Train.. will there be a potential difference created between the trains for a long distance be known ??? till what distance will the potential difference act???

[@pizzapizza3293]

sir in the example of wheel you said the total potential diffrence between axel and rim is=e,and you said that this will be true whether there are 1 or 10 spokes,and if we connect a resistance across it then ""current produced in the two cases will be different"" but sir how is it possible to have different currents when our resistance and emf is constant.

[@pizzapizza3293]

sir when should we take direction of current and e to be opposite?????i.e.use formula i=( - e/R)??????

[@pawanpanjwani7373]

sir while derivation of motional emf u said thad emf will be generated in coil because of motion of one side sir now as this conductor is carrying current wont it will experience a force which opposes its motion and sir will work will be done to overcome this and from where this work will come

[@Priyanshithebest]

Sir what is the nature of the electric field due to induced emf in a conductor?We were told that is non conservative in nature and forms closed loops.Is it true?

[@urvitandel4452]

does emf depends on epends on cross section

[@parthnarang17]

Y hav u used right hand rule here?

[@Success777777]

sir for the motional emf graph ie in the case flux vs distance why do we have a constat flux where we do not have mag field we should have a zero flux over their right???

[@arupkarmakar1862]

Why charges separate in rod

[@Sumonlaly95]

Sir aap 34:35 ne Bola current alag alag Hoga alag alag cell ke liye... But why...??? Whole cell are parallall cunection so it's emf will be "e"....(I=e/r here e and r constant) Aap Jo Bola o series ke liye applicable hai.... Plz help me....I confuse Any body hlp me plz

[@VikashKumar-fv4mo]

sir isma apna Jo aeroplane wala example dia. ki uska dono wings me emf generate hoga. to agar ham iska dono ends se ek wire laga kar ham ek bulb lagata h to kya current isma flow karega. agar nahi to kyu

[@urvitandel4452]

does emf depends on cross section

[@AmanRaj-iv1cj]

Sir Ji your teaching method is great

[@Success777777]

sir can we have power without current but with emf ????

[@MSapp5]

Thanks A TON for these videos Sir!! Helped me a lot!

[@puru98347]

Sir , why havent we considered the cos component in the derivation of blv , i.e initially you have wriitten flux linked as only BA but as we are not dealing with vectors sholuldnt we have written the cos component , also doesnt the cos component come out to be 90 as b , l and v are mutuallly perpendicular so acc to BAcos(thetha) we get 0 as cos90 is 0?? Please help as this is causing some major confusion in my mind

[@puru98347]

sir but cos 90 is 0

[@puru98347]

okay thankyou sir

[@itaps1000]

excellent sir.....

[@paprichakraborty2130]

sir, I follow your class regularly and it helps me a lot for my physics study. Now i am facing problem for my maths , Sir please tell me the teacher name who is Uploading Maths classes in KZbin like you so that I can follow those classes. Papri Chakraborty Kolkata

[@tanhadil2144]

Sir why do we take average velocity ?

[@kids-wk7of]

Best concept to teach.........

[@96srikanth]

excellent sir..

[@4710-h9o]

sir their should be -(- B.l.dx /dt) ????????? only - i s not their thank you sir

[@nayanikamadaan178]

At 29: 55 Why have we taken flux 2 as 0 and flux one as Bπl^2 ....it should be reverse right? B' Coz it cuts the area after completing a circle and initially it's zero (i.e. flux 1 is zero)....

[@niharikakashyap3633]

Nayanika Madaan final 0 hi hoga bcz initial bπl^2 me ghum k 0 pe rukega...so final mag flux will 0

[@uzairalam7878]

Love from pakistan sir u r awesome with physics 💚

[@archana5686]

thank u sir for helping us......

[@Bhargava1995]

the video's are really very helpful in revising thank you sir.... :)

[@bhaskarpurohit7556]

sir, can i get all your lectures of class 12 in cds because i dont have a good internet connection

[@aashutoshkrthakur2692]

frm where can we buy that

[@rakshitmitra145]

sir your videos are very good but they will seem to be better if there is no noise in the background,as because it sometimes becomes difficult to understand in huge noise but otherwise your videos are best

[@riteshvishwakarma601]

Sir hindi video nhi h kya

[@rameshp4897]

Sir one request can you solve the example 6.8 pls sir

[@aishwaryasathya9120]

Thank you for this sir!

[@rajatgupta2268]

Thnxxx sir...

[@gulzarhussain7840]

sir mery physics k concepts weak hen is k liay koi help kr den mn Bs physics ka student hon

[@Harshjot]

sirji u r great👍👍👌

[@titujha4965]

awesom

[@bhavyaarora4027]

sir isn't flux equal to BA.cos theta ? (@4:15)

[@shikharrai4854]

thnxx bro .. i thought i was a goner there .. iwas nt able to undrstnd dat..

[@vemulaakhila493]

yes your correct but the angle between flux and area vector are perpendicular in motional emf so we get cos0 = 1 .area vector is always normal to plane.so there no need of taking cos value.

[@niharshah079]

thanks sir...

[@ritusaini2356]

Sir, This is ritu, a big fan of ur teaching Sir could you please send ur notes

[@gargychakraborty2175]

hats off to u sir....after seeing ur videos i really feel confident among 10 people.....sir can i get ur notes

[@RajeshKumar-te2th]

i need ur notes sir plz.......ur teaching method is awsm
