omg thank you so much. taking calc based physics right. have a final in 2 hours. had trouble throughout the semester trying to figure this out. finally got it! thank you thank you thank you.
Thank you so much. I read this part in my physics book twice and i got the general idea right but that book is still horrible at explaining some of the important things like this. I don't understand why books can't just explain it as simple as this. Thank you so much! I pray that you write a physics book where you explain a lot of stuff just like this just as simply. I would buy it in a hurry.
Why waste time writing physics textbooks if he has already recorded the entire physics course on youtube? This channel + Wikipedia + some Quora/Stackoverflow is enough to learn physics at a level enough for 99% of physics-related tasks.
Thanks, I was really confused about this and now I get it. Your teaching style is unique in that you are very structured which helpful. Keep the the good work
he's doing it wrong. You need to point your thumb in the direction of the magnetic field, thus outwards. Your curled fingers then show the direction of the induced current which is counterclockwise
@@RaoulRamsaran Exactly! I was also thinking about that. What confuses me more is that, he uses the same right hand but the first time thumb indicates the direction of the current, whereas the second time he uses right hand rule, this time four fingers show the direction of the current.(
Question: How can you say that the B field is "decreasing" in the example?Though,i agree that it is "changing" ,i can't get why is it decreasing exactly.
The B field remains the same. The magnetic flux is decreasing due to decreasing of effective area of intersection between the closed loop and the magnetic field.
When any surface move towards to the magnetic field then number of magnetic lines passing through the surface will increase means flux would increase and if the surface moves away from it then flux would decrease due to the decrease in number of lines passing through it
Where is home? :) Sorry for the channel badge, you can mute it by turning annotations off (although if you do that you might run into the problem of missing some annotations, but those are pretty rare anyways).
AK LECTURES: Can you please answer the following questions regarding a transformer video? The video is: ruclips.net/video/ZjwzpoCiF8A/видео.html (reference the diagram at 5:09) Here are some questions: 1) Is the induced current (upward) erroneous? (Shouldn't it be downward making this a non-inverting Xformer?) 2) I presume all that is required to change inverting/non-inverting is changing the winding direction on secondary?

From a hearing impaired person, thank you for taking the time to be clear and loud enough!

Thankyou so much mister...I can't explain how much u have helped me in removing confusion regarding this lenz law....Thanks a lot!!!
How exactly does the thumb point anticlockwise? I can't seem to picture it correctly. Thanks
he's doing it wrong. You need to point your thumb in the direction of the magnetic field, thus outwards. Your curled fingers then show the direction of the induced current which is counterclockwise

@@RaoulRamsaran Not quite, people use the right hand rule differently. You see, in this case, its he points his thumb "up"
why don't teachers in india explain it this clearly ! Thanks a lot
I have to be honest it feels like I'm getting yelled at
+aziz alshahrani hahahahaa xD
getting yelled at with knowledge
your method is awesome and so is your explanation...
Excellent lesson, thanks!
+justin joy Thanks!
I love this, thank you
Great lecture..
I understood!! thank you so much
hope you are our professor! Then I can probably get an A!
Love from India 🇮🇳
This is really helpful! Thank you so much! :)
Excellent explanation. Thank you.
If there is a wire in which electric current is increasing,in which direction will the induced current flow in a circular loop kept near it?
great explanation!!
Great explanation!!!!
Mahmudul Hassan thanks!

I think it must increase , why is it decreasing :(
sir if there is no magnetic flux is present then is current produce in the field????
thank you very much mate
Very clear. Tnx
Very useful!
great lesson
+Tsuyoku- Kun thanks!
why the current is anticlockwise not clockwise
Thank you sir!
Very helpful
Thanks
eldhand welcome.
good explanation
Thanks! Glad you thought so.
thanks broski
How do you know that the flux is decreasing? I didn't get your explanation
When any surface move towards to the magnetic field then number of magnetic lines passing through the surface will increase means flux would increase and if the surface moves away from it then flux would decrease due to the decrease in number of lines passing through it
life saver
thank u!!!!!!
You are making me nostalgic for home...lol. Your channel badge is covering up points on your white board. You may want to remove that. TY!

👍👍👍
This guy's hand gestures resembles trump's gestures a bit
could have explained it in a much simpler way
please reply
Can you stop screaming at me?
ihave3heads no! ;-)

sharif jahan yup.
please reply
