- In this video I explain how to find the direction of the induced magnetic field caused by a current using the curl right hand rule. I do some examples at the end where I solve problems using the curl right hand rule.

doing gcse physics and just realised this was ib...somehow you have made it so it makes sense even for me xx
Honestly this is a blessing, Thank you so much.
Got my GCSE Physics in 30 mins. Lifesaver 🙌
Lol
I just want to say thank you soooooooo much for all the video. I am predicted at a three for sl physics by my teacher on April, but after exploring your videos and try hard for the exam, just find out that I get a seven for physics (may 23)! I really appreciate it!
Aw that's amazing! Fantastic work, I'm so happy these were helpful!
i am predicted a 3 and this comment just gave me hope!!! great job!
Your a blessing dude....thanks❤
The last of the four examples is ambiguous. You can interpret the drawing two ways. In the video you interpret it as the first coil on the left passing in front of the arrow, but it can also be interpreted as passing behind. (You do mention it, but a real test on the subject would have to use a less ambiguous illustration.)
Right I agree, that part of the video was definitely rushed and I could've drawn it much better. For anyone reading: the coil should be read as going into the page on top and out of the page on the bottom, but unfortunately from my picture alone there's no way to know that.
This comment saved my confusion! Thanks to both of you!
Dude !thank you it helped me a lot .
Thank you very much. It's really really blessing. 🙏
Dude, thank you so much!
I don't get example one, he said if went in from the right side and went out of left but drew it from opposite in a way that it looks like it goes in from the left side
he made a mistake
Helped me understand fingers torwards paper
Bro's a genius.
THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU
big help! thank you!!
No problem
Thank you, ,it helped a lot .,🤞🏽
Thank you so much sir ❤❤
Good content andrew
From 2:59 Can you please explain why you flipped the right hand curl rule and let the thumb be the field, and the curled fingers be the current?
It's because the rule works in both directions. If either your magnetic field or current is circular, you can find it using your fingers, and if either is straight, you can find it with your thumb.
See 0:51
very helpful thanks
M23 physics was just today and I wanted to go back to one of your videos just to say thank you for helping me (and many others) get through 2 years of IB physics; wouldn’t have made it this far without your videos. You deserve the world, Mr. Masley 🫶
A good tutorial
All gangsters are secretly just physics majors
thank you so much
Conventional current ? Or electron flow ?
Just to clarify things if you dont know the direction of current flow, then you cannot apply this right-hand thumb rule?
It’s been baffling me as well. Nobody really explains it properly.
No, to apply right hand rule we have to know the direction of current flow. So to clarify, think current and magnetic field as a circle and its center.. So if you have to draw a circle you need to know where the center is.
if you know the direction of the magnetic field you can determine the current direction
If you know the direction of the magnetic field you can use that to find the direction of current and it works. As an example, if the magnetic field were a counter-clockwise circle, the current would be pointing out of the page toward you.
Is this conventional current flow or the negative to the positive?
Conventional current goes from positive to negative, actual current flow is negative to positive.
Does right hand rule works for conventional flow of current or electron's s current?
Conventional! You can use the same rule but with your left hand for electron flow
@@AndyMasley Just to explain to others reading this, Benjamin Franklin guess that current flowed from positive to negative, so that's how it was initially defined (aka "conventional"). But the actual thing flowing are the electrons jumping from metal atom to metal atom, from negative to positive ("actual" flow in this conversation). The right hand rule is using the old backwards terminology (current flowing positive to negative)
thank you
Well nicely illustrated but the fourth example! shouldn't the magnetic field go to the right side because of the current that is going from left to right, depending on the right hand rule??
@@AndyMasley well thanks for the reply but i am confident that if you draw the current to the right then your example would be right because of the right hand rule.and correct me if i am wrong ? Thanks for replying so fast i really appreciate the effort you put to this channel thanks.👍
@@AndyMasley I don't understand with 4th image. What I can conclude is when u use thumb as current flow, the the magnetic field will be to the right. But if u point curret flow to 4 finger, the magenetic field will be to left. So which is true?
This concept same with solenoids, But i think we shouldn't flip the curl right hand concept. Thumb is for current flow, and another 4 finger is for magnetic field.
For the thumb as magnetic field is false.
Sorry I dont understand the last example
Same
This may be a year late but it’s basically the opposite of the rule now thumb represents magnetic field while the curl represents the current, instead of the vice versa.
@@iriri111the curl part twisted my brain lol. Took me 5 min to figure out the direction of the current
In the last example, the direction of the Magnetic Field is opposite, from left to right
The example's drawn poorly I agree, but if you have a curled wire that's going into the page on the top and out of the page on the bottom, the magnetic. I was trying to convey that in the picture but it wasn't clear.
Okay good, I was thinking the same thing, thanks
After 3 minutes confuse me
thanks
In the first example I got confused on why you made it go clockwise when my thumb made it go counter clockwise 😢
Thank you 😊 namaste from India ❤️🇮🇳
if the direction of current if upward then please explain how magnetic field is clockwise in first case u explained
@@AndyMasley ok thank you
Hey im from Pakistan and this helped me thank you. But i cant understand the last example
where does the direction of the magnetic force goes?
I think It is solenoid ithas slightly differ from straight wire current carrying conductor
In first example the direction has to be clockwise
Direction on field in first example should be other way than your arrows would suggest
The arrows are just an added visual to the 3D vector symbols, focus on those first. It's not really possible to draw clear 3D arrows, it was my attempt to make it a little more intuitive but I can see how it would be confusing
@@AndyMasley thank you, good video
@@AndyMasley Ah, thanks for clarifying, that one got me confused a little hehe. Good video btw :D
It is called Maxwell right hand thumb rule
strong right hand produces a huge magnetic flux
But where is north?..
2.10 arrow mark of the magnetic field is wrong
Are finger tips north pole
@@AndyMasley ред huh
Kk
The magnetic field always points in the direction that the north pole of a magnet would be pushed by that field.
You already speak English. Part of the image cannot be seen due to caption screening. But thank you very much for it work
@@AndyMasley jhkj
You can turn the captions off using the CC button at the bottom right part of the video screen
Gu e o cafezinho tava no forno e o cafezinho tava precisando muito muito sucesso e o cafezinho tava precisando de um beijo no rosto e é só r viu se
u explained a bit confusing.. although its an easy thing
Example 4 the field direction is rong .
it should be in the opposite direction at the right 🤔🤔
F da vida da vida de um beijo e o almoço de hoje né a noite a todos da família e o cafezinho da tarde e é o almoço
D ER r viu o almoço e é só no é o almoço amanhã de manhã r da manhã e o almoço amanhã de manhã e o cafezinho tava precisando de alguma coisa e é só
Thank you you saved mee 🫶🏻
