Nope, you will. Your working hard and trying to sort out the material yourself will do so. I'm just happy to be a part of it. Go show those exams who's the boss! :) Cheers, Mitch
A really cool trick that comes in handy and also allows you to not use the left hand rule is: switching the current (thumb) when you have an electron. So if the electron is going to the right, you move your thumb to the left. This way, you only have to use your right thumb and not make silly mistakes like using the left hand when you want to use your right.
I was so confused using the "classical" left hand rule until you explained your version of it - I guess you and Darth Sidious for the win! Thank you so much for being such a helpful resource for revising for my final IB exams.
Can you please quickly give me an explanation for 7:09? When I'm doing it, the normal flemings left hand rule shows me that the force is upwards. And I'm worried now. Thanks
I believe it's because the electron is going to the right, however conventional current (The one used in Fleming's LHR) is in the opposite direction to electron flow - Electrons flow from negative to positive but conventional current is positive to negative - Therefore the current in the LHR should actually point to the left which would make the force point downwards.
Just a question, which hand rule (and how should you apply it) if you are given a question that gives both current and velocity and asks for the direction of the magnetic force on the electron?
Depends entirely on the specifics of the question. What you designed sounds like it's not likely, as you'd need EITHER the velocity or the current, but not both. If there are forces on the electron, it's pretty much always going to be Hand rule 3 (since it has a force). The other two hand rules have current and magnetic field, but not force. Hope that helps!
@@OSC1990 That's also why I was confused, I reckoned this would be a very rare scenario of a question. The question literally asks: "A long straight vertical conductor carries a current I upwards. An electron moves with horizontal speed v to the right. What is the direction of the magnetic force on the electron?" - the question also draws a diagram with lines of current pointing up and velocity with an arrow to the right (perpendicular to current).
Hi amazing video by the way, but I was confused for your second example where you said that current flows from the negative terminal to positive. Shouldn't it be conventional current when we use right-hand rule?
@@OneOpportunityaDay If you use the hand rules as I have them in the video, they will work on the IB Physics exams. We use the Left hand "star wars" rule with electrons or negative particles only. We use the Right hand rule for positive particles. **We also use the right hand rule for current, because the IB Physics course uses conventional current (which is the direction of positive particles). What's interesting is that we have known for a VERY long time that current is ACTUALLY electrons flowing. But the good news for you is that if you use the rules exactly how I describe them, you'll be able to solve all the exam questions (I've used them on all the exams so far and they work great)
Thank you so much for the kind words! You can support what I do by considering OSC Study - it's a real passion project of mine - we just added a bunch of Paper 3 solutions for Physics HL (SL should be added this week): app.oscstudy.com
can the current also make it curve to the right or does the velocity only do that? also the proton/electron doesnt have to be to the left of the magnetic field for the question to say it move to the right ?? right hahahah thanks a lot your videos are really helpful
Hah! Doing physics in practice is still a key part to your education, so working with your teacher on actually trying things out is important. Glad to be able to help you though! :)

How does one make a physics video so educational, nerdy and wholesome at the same time
I genuinely love you so much man, we need more teachers like you in this world.
happy to help! Cheers, Mitch
I really apreciate the good vibes you make your videos with, keep up the good work.
YOU ARE THE BEST, I HAVE STRUGGLED ON THIS TOPIC FOR SO LONG. Seriously, thank you so much, best teacher!
I'm so happy to help!
you're an amazing teacher and your channel deserves way more recognition, x
Thank you very much - you're welcome to tell others about the channel - I'm so happy to help as many students as possible. Cheers, Mitch
hi mitch, just finished my paper 2 a few hours ago and i want to thank you for everything, you're the reason i survived ib physics!! thank you 😭❤️
You are so very welcome! I hope the Physics exams went well! That's one less subject to worry about now. You've got this!
This is actually life saving, thank you.
this guy is gonna single handedly get me the 7 in the IB exams
Nope, you will. Your working hard and trying to sort out the material yourself will do so. I'm just happy to be a part of it. Go show those exams who's the boss! :) Cheers, Mitch
You're genuinely the reason I'm finally understanding IB physics! Thank you so much 🙏
I'm so glad I can help! :)
man you're the best
Thank you so much!
this strategy would be perfect if the physics IB exam was on may the fourth *(may the fourth* be with you).
:)
Nice one!
It's one day too early then (3rd may) :)))
This is amazing!! ❤
I'm so glad you like it! :)
awesome video. Thank you for explaining this so clearly. You make physics entertaining and much easier to learn.
Glad you liked it! Cheers, Mitch

I'm so glad the video could help you! Good luck with your exam preparations - you can do this! :)
Seeing this hours before the IB exam, and the Star Wars Rule was so helpful! I always forget how the 3-finger Right Hand Rule works.
Glad I could help! :)
Thank you so so much! You helped me in my exams. Continue to make such content, you're awesome
Power! Unlimited Power!
omg I love u teacher that starwars thingy is so catchy thanks so much

Well explained!
Thank you so much for this video. Very helpful and fun. The vibe is great!
Glad it was helpful! Cheers, Mitch
Thanks to you I got 7 in physics HL!
Congratulations to you! So glad we could help you out in any way

This right hand rule trick is so good, Its so easy to remember
I'm so glad it helps you!
I wish my school teachers were this fun while teaching...great content man
I appreciate that! Cheers, Mitch
got an exam today and my teacher has taught us nothing 😭 this playlist has taught me more in 2 hours than I've learnt all year THANK YOU
I'm so glad I could help you! Cheers, Mitch

in part one of hand rules

Thank you so much, just had my test today!
blew my mind
i love this man.
This man loves you right back! :) Cheers, Mitch
Mitch you are the GOAT is there any way i can support you better
Thank you so much for the kind words! You can support what I do by considering OSC Study - it's a real passion project of mine - we just added a bunch of Paper 3 solutions for Physics HL (SL should be added this week): app.oscstudy.com
not to be rude, but there is actually already a rule called 'the right hand palm rule' which is exactly lke the one that you said.
It's not rude at all - I'm just trying to explain things as clearly as possible for students. I'm glad you already know the palm rule :)
I would get a full time job pay to have this man as my tutor...
Hah, thanks! Cheers, Mitch
can the current also make it curve to the right or does the velocity only do that? also the proton/electron doesnt have to be to the left of the magnetic field for the question to say it move to the right ?? right hahahah thanks a lot your videos are really helpful
it's not the velocity that makes the particle curve, it's the force. Kind of like centrifugal motion. Velocity perpendicular to force.
Thanks a lot
You're very welcome! Cheers, Mitch
cannot thank you enough
You're very welcome! Cheers, Mitch
this is really interesting！how humorous LOL
Glad you like it! Cheers, Mitch
I GOT DA FORCE WOOOOOOOOOOO thx much sir!!!!
You're so welcome! Cheers, Mitch
AMAZIUNG
Thanks! Cheers, Mitch

Who needs to go to school when you have osc
