Thank you so much this is so helpful. I literally was about to cry cuz I spent an hour in class trying to figure it out and my brain couldn't comprehend what my teacher was saying. You have great explanations!!!
So many years of forgetting this and bending 3 fingers at awkward contortionist angles, now I’ve got it after your great video, thank you very much, good job..
The right hand rule can be very confusing. You did a phenomenal job at explaining the rule. The problem is the relationship between the 3 aren't 2 dimensional. Too me a while to learn. Technically the current goes in a 3 dimensional circle around a wire. It up it down or it's left or right depending on how the wire is orientated. Then there is a coil of wire. That is used for many applications. Great job.
@@kanokochan8671 No. that is not what she said reply it. She says the magnetic field is pointing inn and a current is pointing upwards is what she said. That means the force is going to the left.
Thank you, I greatly appreciate this even though I am not from your school. This has helped me better understand physics with more knowledge and understanding compared to what my teacher has said. Thank you
Why use the thumb for the current? My class is saying point our fingers in the direction of the current curl them towards the magnetic field and your thumb points to the force
Could I ask you please when I’ve been looking at animated generators and motors videos with their right hand rule using the three fingers the force is opposite to your right hand rule, I have to use your right hand rule for their motors left hand rule, I’m not nitpicking and I’m still going to use your method as it’s so easy to remember and understand, but I cant understand why I have to reverse it for all the other videos I see, please tell me if I’m missing something, thank you very much
There are different perspectives depending on where you are relative to the sheet of paper. For example, if you are looking down on the sheet of paper, then you need to clarify does "up" mean "towards the top of the paper" or does "up" mean "out of the paper and upwards compared to the desk surface". In this video, I used "up" to mean "towards the top of the page"
Is the American way of representing the Right Hand Rule? In IGCSE we use the middle finger, index finger, and thumb to represent current, magnetic field, and Force respectively. Interesting.
downward as in toward the bottom of the page or bottom of the screen. Look at how my hand was oriented in the video: fingers out of the screen, thumb to the right, and palm of my hand down toward the bottom of the screen.
If you understand cross product properly you'll understand that the result will always be perpendicular to both vectors, so you basically exclude 2 directions, the exact direction comes out from the math itself.
Yes, the right-hand rule can be thought of as a physical representation of that cross-product math. Many of the introductory level physics courses may not cover the cross-product math, and even with the math using the hand can be a faster way to get the direction once you get used to using it.
First, note that I use up to be toward the top of the screen or paper and down to be toward the bottom of the screen or paper. In most of these problems, they will tell you the direction of the magnetic field and the direction of the current, either in words or in the diagram (the wire is shown vertically with an arrow showing if it is up or downwards). Then you have to find the direction of the force using the right hand rule as shown in the videos. Sometimes, they will give the direction of the force and direction of the current and you have to work backwards to find the magnetic field. It would be rare that they give you the force and magnetic field and you need to figure out the direction of the current.
Last answer force vl be in left direction..## @jenifercash..plz reply mam nd thx alot ...I hv been suffering for this since a long time now it's cleared I m a neet aspirant🙏🙏🙏
My teacher has explained right hand rule SO many times but I still couldn’t get it. Now I do! Thank you for this
Cuz we all understand only through utube
This is true @@benitamehala5744
Thank you so much this is so helpful. I literally was about to cry cuz I spent an hour in class trying to figure it out and my brain couldn't comprehend what my teacher was saying. You have great explanations!!!
I feel your pain😭
I didn't understand the right hand rule even after my prof and the TA explained it. Thank goodness for this gem of a video!
So many years of forgetting this and bending 3 fingers at awkward contortionist angles, now I’ve got it after your great video, thank you very much, good job..
This has to be the most helpful video I have come across. Thank you Ms. Cash!!! The last one is towards the left!

towards left for the last one
Sakshi Jha yupp
because the current is upwards and B is out of paper
She said the tip is pointing towards you so its coming out which then according to the right hand rule the force is towards right...
@@kanokochan8671 No. that is not what she said reply it. She says the magnetic field is pointing inn and a current is pointing upwards is what she said. That means the force is going to the left.
@@aakashiTutorLecture i think so
Thank you! My physics professor explained it just using thumb and fingers but it makes more sense to use the palm to indicate direction of force.
Cannot thank you enough, I have my SAT Physics tomorrow
This was the most helpful video for the right hand rule!! Thank you!
So, in the last question, the force is on the left, correct?
Well explained 👍thanks 🇵🇰🇵🇰🇵🇰
You are a life saver!! Thank you so much for posting this
Thank you, I greatly appreciate this even though I am not from your school. This has helped me better understand physics with more knowledge and understanding compared to what my teacher has said. Thank you
I finally understand this, thank you
same here!!!!11!
This was the best explanation! Thank you!
It was really usefull
2:43 thank you! I was about to break my hand doing this
Best explanation ever❤
How do you know weather to place you hand to be facing upwards or downwards ? And is it always the right hand that you use?
this was so helpful thank u... also you kind of sound like ellen degeneres it was very comforting lol
Thank You @Jennifer Cash had struggled a lot for these notations until I watched your Video
Maam I bet you are one of the star teachers in your community.. awesome explanation 😍😊😊😊😊
Thanks so much. This cleared a lot of confusion
Why in the last one it is at the left ?
Thank you!!!! Does the palm trick work with other forces, say B V and F or B V and R?
THANK YOU!! I didn't understand this concept until watching your video!
Was the answer to the left the last Question?
is the force going to the left for the last one?
so the answer for the last question would be to the LEFT correct?
I couldn't understand my teacher but thanks to you finally I understand this :)
Is the answer to the last question To The Left?
This was excellent help! Thank you
simply we can say force and magnetic field are always perpendicular to each other if it is not perpedicular there is no force acting
Excellent thnk you very much Miss Jennifer
watched so many videos & didnt get it until this one.. thank you!
Thanks a lot....I was puzzled for a moment until I saw you video
ay but for the last example is the force 0??
bless you for posting this video!
this video saved my life
Is this defined for negative charges of positive?
Great video, but I thought the dots represented direction of current not mag field?
What does it mean when it's into the page or out of the page?
Thank you. Can you explain the relationship of the Lorentz Force and the Right Hand Rule? Or is there one?
this was extremely helpful!
Great explanation ! helped me out so much !!
I think force is towards left side perpendicular to current . Plz tell me if I'm right
Why use the thumb for the current? My class is saying point our fingers in the direction of the current curl them towards the magnetic field and your thumb points to the force
Awesome!! Thank you for the video. It is much more clear
Thanks, I m not going to forget this in future😊
Thanks! Makes so much more sense now
Superb 😊👍✨
Could I ask you please when I’ve been looking at animated generators and motors videos with their right hand rule using the three fingers the force is opposite to your right hand rule, I have to use your right hand rule for their motors left hand rule, I’m not nitpicking and I’m still going to use your method as it’s so easy to remember and understand, but I cant understand why I have to reverse it for all the other videos I see, please tell me if I’m missing something, thank you very much
In the last case.....is the force going upward?
When the magnetic field is going inside the page
I guess is it right ?
Thank you so much mam. Your lecture is helpful. Love 💖 from Pakistan ❤️
Thanks for your nice video, the force is going to the left side
Wonderfully explained🙏🙏
Thanks a lot you made things a lot easier to understand
Thank you finally I got it 🎉
great video
simplet yet helpful. Thank you so much!!!
Whats the answer for the final situation
how is the last one downwards???? that doesn't make sense
what is the difference between outside the sheet and moving upward or downward?
There are different perspectives depending on where you are relative to the sheet of paper. For example, if you are looking down on the sheet of paper, then you need to clarify does "up" mean "towards the top of the paper" or does "up" mean "out of the paper and upwards compared to the desk surface". In this video, I used "up" to mean "towards the top of the page"
Thanks a lot for this video. You are a skilled teacher.
Hey Jennifer Cash, is the answer zero or to the left for the very last problem?
The force is to the left for the last one
Thanks for taking the time to reply! I appreciate it! :)
Tks from Brazil!!!
I think force is towards left ! Can you plz show us the ans?
This way just , when the angle between velocity and magnetic field equal 90
Is the last one no force because magnetic field is down and current is 180 degrees?
Yeap. If they are parallel, there is no force or equal to 0
Thank you so much, I have SATs in 2 days and I kept confusing the right hand rule for the inverse of the left hand rule
Thanks again.
Thanks
very good method to Conway
this is so helpful. T^T Thank you so much teach.
Thank you MS
Thnks very much it really helped me so much
Thankyou 🙏
Thankyou so much
god bless you for real
thank you
Thank you!
What was the answer to the last one?
Force is zero in the last case as the angle between magnetic field and current is 180
Force is towards the left
The force is to the left for the last one
Arnavi Lol...no
Towards left
Thank you! Finally!
Is the American way of representing the Right Hand Rule? In IGCSE we use the middle finger, index finger, and thumb to represent current, magnetic field, and Force respectively. Interesting.
This is the right hand slap rule
What happened to the video?
is this conventional current?
Yes, the thumb direction is the conventional current
It's out side the sheet
Nice Explanation buti think this is right hand Palm rule
Hi mam i dont understand what is the meaning of the page or screen what is it? :)
you are amazing
Ty kinda get it now
Thankyou so much. Appreciated
How force is downward in 2nd last case??
downward as in toward the bottom of the page or bottom of the screen. Look at how my hand was oriented in the video: fingers out of the screen, thumb to the right, and palm of my hand down toward the bottom of the screen.

how we will know that current is up or down
First, note that I use up to be toward the top of the screen or paper and down to be toward the bottom of the screen or paper. In most of these problems, they will tell you the direction of the magnetic field and the direction of the current, either in words or in the diagram (the wire is shown vertically with an arrow showing if it is up or downwards).

It would be rare that they give you the force and magnetic field and you need to figure out the direction of the current.
finally, it all makes sense
Super thank you
Thank you so much I needed this thing so badly😊😊
Last answer force vl be in left direction..## @jenifercash..plz reply mam nd thx alot ...I hv been suffering for this since a long time now it's cleared I m a neet aspirant🙏🙏🙏
To the left 👍🏽
Thanks!
