Flemmings right-hand rule confusion: There are two Flemmings hand rule. The left-hand rule and right-hand rule. The left-hand rule is used when an already current carrying wire in a magnetic field experiences a force. This is the case in motors. We pass current through the coil and the force due to field pushes and turns the coil. However in generators, we turn the coil and as a result, electric current is produced. To figure out the direction of this current, we use the right-hand rule. Hopefully, this clears the confusion of why we use left-hand rule for Motors and right-hand rule for generators.
Appreciate video content! Excuse me for the intrusion, I am interested in your opinion. Have you ever tried - Elijahzan Ailment Solution Review (just google it)? It is a great one of a kind product for saving money with your own electricity supply minus the headache.

Thank you so much khan academy ,for removing all the doubts of the students like us who face difficulty in understanding electric generator and motor. The animation were so perfect we didn't even get confused for were the current is flowing.....thank you once again khan academy
I'm having a hard time paying attention in class recently, I got stressed when I couldn't figure out my homework questions. This video cleared up lot of my confusion. I feel more confident in understanding how generators work. Thank you Khan Academy, you've helped me with math and physics many times now.
This explanation just made me secure a job. I watched this video about a week before the interview. During my interview the only technical question that was asked was for me to explain the simplest way of generating electricity. Believe me I nailed it.
Hey, here's a dedicated CBSE course on our website where you can practice all the concepts related to this video and more. And oh, it's always free. www.khanacademy.org/science/in-in-class10th-physics/in-in-magnetic-effects-of-electric-current
This man is the best teacher I've ever heard. This was made so crystal clear, my 11yo son could understand it and use it for his science fair project. Thank you, sir.
*Wow! Even if nobody will believe, i have searched and searched this thing for a long time. Since my childhood, that how stuff works; ive never came across someone who can explain with such an ease that even a child gets it. Thank you so much. I searched any but all gave book terms and jargons. No one actually knew how the frequency is there in AC. I was hoping to get the answer someday.* U know the feeling that when you want to get the answer to your question for years!!! Literally goosebumps!!! Thanks 🙏 today i learned about frequency in electricity. I have one more question that bugs me. That how in computers the circuits automates things. Like i know that we program them chips and all. But still, who does the automation? Please point me to the right direction.
Thanks for sharing, I am glad it helped. I remember seeing an old (and lengthy) video by Richard Feynman explaining how computers really work. Maybe that could help.
Khan Academy India - English thanks much. I searched. And found this. ruclips.net/video/EKWGGDXe5MA/видео.html can you plz check if this was the video you were talking about?
Khan Academy India - English thanks i watched it but it doesn't has what i was looking for. *Im not sure about one thing! Who controls these automations in chips? For ex: If i switch on a light bulb. I have to manually flick the switch ON to make it glow. But in computers i don't understand how they do it automatically? I want to understand how they do it. Is a something related to the chemicals used in chips or some thermo electarical thing which open and closes the circuit ay a desired temperature???* These two questions have bogged me for like ages. You solved one but this second question is driving me nuts. Plz if you can; I would really appreciate that.
@@jemsncrystals What do you mean by "do" when you say "how they do it automatically"? Computers require manual input too! You need to turn them on/off, type and double click on stuff you want them to run, etc. I guess you want to know when a program is running, who is, and how is it running that? What exactly is a program, anyway? - These are deep and curious questions that are beyond my domain of expertise, but I can give it a shot. Instead of a switch connected to a bulb, imagining 100s of billions of interconnected switches. Imagine turning on/off a switch can cause other switches to turn on/off, which could cause still more switches to turn on/off. This 'domino effect' is what I like to think of what 'running' a program means. So when you turn on the computer, for example, you are manually triggering a few switches, and then the domino effect begins. When it's done, your computer boots up. But again, as I said, take this with a pinch of salt - not an expert here. Do ask more questions! This is interesting!
No channel...in the RUclips....has created like your animation....for understanding...this. Concept....really great work, thank u my dear friend....really thank u it helped me a lot...and from now iam your new subscriber and I will share this to my friends
I learned this theory 60 years ago; L.H. rule for motors, R.H. rule for generators. As I didn't go on to work in the field I didn't ever fully get to grips with it, and have puzzled with my memory of it over the years. As I see it now, even a D.C. generator generates in A.C., the commutator acting to correct the A.C. to D.C.! Beautifully explained, thank you.
This is without a doubt in my mind the BEST explanation of magnetism & induced current and direction that I have ever seen. This is so superior to virtually everything else I have seen I have to wonder why no one else could explain it this well?
Thank you so very much Mahesh and your team. It was indeed an excellent explanation with loads of patience and intricate details where children and even adults might get confused.
i have been studying o level physics for a year and i was never able to truly grasp what was going on with the generators. but with this video when tomorrow's the o level physics CIE exam I have finally understood it. tysm khan academy
When i was a university student in 1980's without internet only with books / static images, to learn this things it was 100x more dificult to understand these basic concepts then it is today and for sure it took 100x more time than nowadays. Congratulations for the video.
sir, the explanation and the way you have presented this tutorial are very good for students. learning by visualization is the best method of studies. Students should explain this concept to others which will definitely be useful.
Before watching this video, it took me 5 days to understand what and how an alternator and dynamo works, but after watching this video today I now finally understand. I greatly thank you for this video. This will greatly help me during my GCSE's exams I thank you so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so so much
I don't usually comment on videos, but this video made me comment! Your teaching skills are top notch! The animation was perfect too!! Thank you so muchhh
Just one comment to clear up my confusion. Your video never distinguished between conventional current and actual electron flow. I will assume that when using flemming's right hand rule for ac and dc generators that you are using coventional flow of electricity from + to - . Wonderful video. It removed the clouds from my eyes and cleared my brain. I am eternally grateful
I'm Korean student and I keep found about direction on ac generator, and I finally found this video. Thank you so much. this video save me from AC hell Thank you!!
Hello!! This is an amazing video. Really helpful and comprehensive! I would like to ask you how do the rotating wires connect to the rings? Are there any smaller circuits inside the rings?
Thanks for the explanation! One doubt, can we also use Lenz's law to take out the dirn of the current? because since the coil is turning, the inward flus increases( since magnetic field lines are from N to S as shown in the diagram) and since flux opposes any change, we can say that an outward flux must be induced resulting ina an anticlockwise flow of Current( from the N pole's side). and therefore the dirn of current in the loop as shown in the video, is it a correct way of thinking?
Which software do you use brother? ..... I want to explain concepts like this to my students. Please reply ASAP as they have their board exam next month. Thank you!
I’ve been struggling with this chapter for the past few months and I watched a TON of vids in the hopes that my brain would process something, but this one lit the lamp. Ty soo muchhh 😭
This is hands down the best explanation along with animation for this topic. This chapter was really confusing for my understanding earlier but it is literally a piece of cake now.
for the love of God give this man an award for such an easy to understand video. I have gone to 3 classes and couldn't grasp the principals of generators, I watch this video now everything makes sense, thank you so much.
When I present during recitation my middle finger to my professor, he said it does not says to point the direction of current, but the direction to go out to the classroom. Why is that?
BEST EXPLANATION EVER!!! I had so much trouble getting my head around the flow of d.c and a.c in the armature. Its do with a.c having slip rings and d.c have split rings. Now I get it, thanks
I spent so long watching pointless videos that don't help whatsoever, and then I found your video. Thank you so much Khan Academy for the amazing and easy to understand explanations and videos!!!
