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.

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.

I have never felt this satisfied ...before ...Thanks to Khan academy for such a content filled video

This video taught me something my teacher couldn't teach me in 1 year. This video did it in less than 20 minutes. Bravo

I just love how you address and clarify every doubt that comes to our minds as we learn these concepts!

The detail covered in that must have been the best I've ever seen.

Congrats man on such explanation! Better then all teachers who just use nonsense examples and overcomplicate. Thanks!

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

we dont deserve this dude, but he's here anyway. Thx man!

This is the only video through which I have now understood about the generator. Thank you!

Finally! It hit a million! A milestone

thank you!!! the animation is so helpful, trying to visualize this through 2D diagrams was so hard

this video is so good, it explains things so well, I think I finally understood how electric generators works

*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.

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!

This is one of the best explained tutorials I've ever come across 💯

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.

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?

The best ever video with a fantastic explanation and awesome animation. keep it up😎👍🏻

How many of u here are watching this video the night before your physics exam??

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.

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 the best tutorial on AC generator I have seen so far.

One of the best video..Thnx alot...your Tutorial is amazing..

helpful for science project

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.

I don't know if you will see this comment but I've seen many videos with exceptional animation skills and great explanation techniques but this is the only video that has made me understand the whole concept of the difference between ac and dc motor and how it all connects to the concept of the fleming's left hand and right hand rule. This is the video I needed, the one I was searching for, for many days. Thank you so much. I was mostly confused on why there was a gap in the split ring commutators and this video fulfilled that doubt (thanks to the pausing you did to show the current reversing direction)

Thank you for explaining so well! I finally understood how AC and DC generators work and their difference!

That was wonderfully explained. You're a born teacher

apart from hand rule explanation.... the video is top top top, understood the concept very easy from first watch... thank you sir!

Are you sure you have the orientation of the current, magnetic field and Lorenz force right? According to the right hand rule: index = current, middle = magnetic field and thumb=force. Or according to the left hand rule: handpalm "catches" the magnetic field, fingers point in current direction and thumb indicates the force.

This video was really helpful! Khan Academy and Sir Mahesh always come to my rescue! They deserve everything in the world for making these videos
