The Curl Right Hand Rule - IB Physics

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.

0:00 Using the Curl Rule for Linear Current
0:41 Using the Curl Rule for Circular Current
1:14 Example 1
2:28 Example 2
2:54 Example 3
3:54 Example 4

I just want to say thank you 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!

doing gcse physics and just realised this was ib...somehow you have made it so it makes sense even for me xx

Got my GCSE Physics in 30 mins. Lifesaver 🙌

Thank you so much! Your representation on the paper made this so much easier to understand

[kashaffiza]

Honestly this is a blessing, Thank you so much.

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.)

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

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 🫶

THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU

Thank you very much. It's really really blessing. 🙏

All gangsters are secretly just physics majors

Helped me understand fingers torwards paper

[saidgafforsabyrov]

In the last example, the direction of the Magnetic Field is opposite, from left to right

[Tautviss]

Just to clarify things if you dont know the direction of current flow, then you cannot apply this right-hand thumb rule?

[vrdlqup]

I think It is solenoid ithas slightly differ from straight wire current carrying conductor

[CB-klew]

Is this conventional current flow or the negative to the positive?

[cymric]

Sorry I dont understand the last example

[t.h.]

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?

[clems]

Conventional current ? Or electron flow ?

[mLee]

In the first example I got confused on why you made it go clockwise when my thumb made it go counter clockwise 😢
