In this video Paul Andersen explains how a charge particle will experience a magnetic force when it is moving through a magnetic field. The right-hand rule is described as a method for determining the direction of the force. The magnitude of the force is a product of the charge, velocity and magnitude of the magnetic field.

My classmates and I call the RHRs the "physicist gang signs"
that's cute

Physics gang wassup
somehow in eight minutes i learned something my teacher has failed to teach for a week straight
Same story here
same smh I got an A last semester and i have a new teacher and this bitch don't teach now I have a D

completely agreed
EXACT same thing happened to me.
**Applause** You managed to teach this concept better than anyone in the physics dept at my university. Bravo!
That's actually a pretty big achievement in my opinion 👏
This is the most efficient way to explain the right-hand rule, great job!
I'm giving you an upwards magnetic force for this comment👍
LEFT HAND RULE!
You taught me AP bio in my sophomore year of high school. Now I'm back 7 years later, and you're teaching me physics for the MCAT. Thank you, Mr. Anderson! c:
how did it go
how'd you do??

@@azndoanln badass. love to hear it! 😁
I've been aware of this concept for over 20 years, but never understood it better than I do now after watching this. Thank you, sir! Perfect presentation style, and elegantly succinct.
that awkward moment when you're trying to do the right hand rule but remember that you're an amputee
You made my entire week with this comment !
you made me laugh and then cry over how messed up my humor is
Oh my God. I dunno if it’s unethical of me to laugh.😂
wtf 😂
You forgor💀
Thank you for this ! I'm reviewing Physics for the MCAT and have never truly understood magnetism because it was poorly taught in my school. Your videos are very clear, with clean animations that help us follow along with what you are saying. Keep it up!
man going thru the same now
Why you seem to be expert in all all the academic subjects? Such a genius....
chemistry especially
agreed
You are my hero! I can always count on Mr. Andersen to explain what others can't. Thank you.
Much appreciated. Online courses don't pair well with explaining a physical concept like this, so I'm glad your video helped me fill in the logic gaps I was having. Thanks!
Bozeman, you killed it. Your videos have been helping me since high school!
I love how concise this video is. I'm just reviewing for My MCAT. Thanks!

I absolutely love physics - but it honestly gives me such a headache...irritating. lol
Bruh I learned the right hand rule in about 4 minutes vs my teacher today who spent about 2 hours (double period) basically teaching us gang signs instead of teaching.
wtf I still don't understand when this man teach feels the same as my teacher
Very helpful! Short but very clear and the graphic help a lot too. Thanks!
That was great one of the best explanation I have heard so far. I was confused thank you for clearing my confusion.
DUDE YOU REALLY DID HELP ! I'VE BEEN SEEING THOUSAND OF VIDEOS AND WOULDN'T FIGURE IT OUT TIL YOU SHOWED UP
That was extremely helpful. In class, everything up until magnetic fields was clear to me. I was having trouble determining the direction of the force exerted on the moving particle through a magnetic field. This video was and is the solution.
thank you so much for this video, other demonstrations were just 2D vector diagrams that i couldn’t really wrap my head around but your demonstration of the right hand video is perfect.
The way of his teaching is incredible! Thank you!
This sir teaches everything in simple words and easy ways and I never get confused. THANK YOU! MAY GOD BLESS YOU.
Thank you very much Prof! You really helped me pass the physics university exam, you have a gift for clarity.
OMG this is so helpful !! I was confused after looking Princeton review and Barron. But this one is so straightforward. Thank u, Mr. Anderson
THANK YOU! Saw my teacher doing all those hand movements and had no idea what he was doing, helping me a lot for my quiz!
Thank you! This makes understanding the "right hand rule" so much easier than my professor and my textbook.
Thank you! My physics professor doesn't know how to teach and this right hand rule explanation actually makes sense
Make sure he never sees that comment
Or she
That was helpful. I've only learned physics in the last year or two, self taught, blowing my mind. I never used to understand equations, now that I do, I can't believe that nature works this way. Thanks.. I'm subscribing.
stuyding for my mcat with this old gem of a vid, God bless you Mr.Andersen
How pleased you are to chop away, Jack the Ripper!
I LOVE your course!!!!!! Thanks so so SOOOO much! Without you, my learning journey will be dark and hopeless😭
This guy's better than Khan Academy.
For physics, yes, I agree. Although David SantoPietro does some really great explanations on KA for physics.
Are you guys kidding? Well, I personally think Khan Academy IS great with this kinda stuff
@@osasdave7517 i think Khan is def great but Mr Anderson is still the best
Obviously on this channel you would hear this.
It's basically confirmation bias.
But Khan Academy is better if you add in all the extra factors, although both of them are great at teaching.
I think that khan academy is better at teaching math than other subjects.
my professor spent a lecture on this doing it a different way, and i understood it so much better in just 4 minutes. andersen ur the real mvp.
This explanation was awesome. Going to ace my physics test now! Thank you
This was a much needed tutorial for me. Awesome video.

If you’re reading the comment section for that ambiguous part of the video in 4:21
Then go back for the arrow symbol explained where the encircled point indicates the magnetic field going towards you whilst the encircled cross sign indicates that it goes away from you (see 1:00)
Note: Middle Finger Indicates Magnetic Field or B
You see the magnetic field direction (encircled points) changes after the first moving charge example (the one that is inclined to the left) into encircled cross (means magnetic field goes away from you) which was the next example that twisted yo mind.
He even said “Now we have a different magnetic field” in 4:11
Then go apply Fleming’s right hand rule and it will now make sense
Thank you so much for this Mr. Andersen BTW
Thank you! I was looking for an explanation to this. Haha I didn't realize that the magnetic field changed and I was so confused. Thank you so much!
Rani Andleeb I’m not too sure but I think the right hand is for protons and the left hand is for electrons.
@Rani Andleeb because the charge of an electron is opposite to a proton so the "current" is technically flipped.
As he said in the video, you could use the same hand as a proton and flip the end result OR you can use the opposite hand
LORENTZ FORCE, GO!

You`re doing a great job here! Thx for explaining so good
I LOVE YOU SOOO MUCHHHHHHH THIS HELPED ME SO MUCH HOLY, my teacher is great but he goes a little too fast and like he doesnt explain properly sometimes, man oh man this is gold
thank you sir, this was very insightful and I learned this concept in a quick and effective manner
Ty I learned in 3 minutes how to do the RH rule finally. Professor and TA's couldn't demonstrate this well for some reason
50,000 dollars a year or a 50 second add to learn. LMAO wtf
This video was BEYOND helpful. Thank you so much. Had no idea what I was doing before I came here lol
Thank you, I really learned in those minutes something that my teacher failed to teach for a whole unit
Great video, I had a really hard time understanding this topic until I watched this. I'm reviewing for a Physics 2 exam and this helped me a lot. Thank you!
Your videos are awesome, ¡keep the good work man! You are a great teacher
I was 9 years old when you posted this video. Now I am 18 and learning from it. Thanks for that.
Your explanations are so clear and helpful
MAGNETIC FORCE JACK, NATURES FORCE!
Exquisite
@@mossfinder7516 LEFT HAND RULE
Haven’t learnt soooo much in so short. Big thumbs up
Thank you! I have an exam in 2 hours and this video really helped!!
This is super helpful. I've always been confused about this but I so get it now. Thanks
Thank you very much, even if it is an old video, it was very useful and simple to understand.
Thanks for a brief and informative explanation!
This really helped me! I thought I would never understand it! Thanks!!!
your visualization of the right hand was very useful, thank you
Really Really inspirational and awesome video. Thank you so much, Really appreciate your effort.
GREAT VIDEO! Thank you very much. short and well explained!
Wow, you're really good at explaining this, damn.
college is an actual scam after watching this, or else the proffesers are just dumbasses
You just relieved a great deal a frustration, many thanks my friend
Thank you for this! I'm a bit confused as to how a permanent magnet works based off the explanation here -- wouldn't a permanent magnet that's not moving (relative to a charged particle) exert a magnetic field, and wouldn't the charged particle feel that field even though neither are moving relative to each other?
Splendid explanation, thank you so much sir. I got every Qs crct , it was very helpful.
I just love your channel, great work
Oh good! When I see it was you I thought GREAT! This guy actually knows the stuff. Thank you.
This hand rule is so much better than the one my teacher taught us. Something about curling your fingers it made no sense to me. Thank u sir.
I learned a similar rule of thumb picking my chassis electrical instructors brain (Whyotech). It's a rule to find the magnetic field in a conductor when you know the current direction. I was Googling that rule when I found this video. Learned a new rule from this one. Subbed. I'll be back for more lessons.
DUDE ur videos are amazing!!! Keep up the good work
this video was SO helpful!! Thank you so much!
Thank you! You are such a good teacher:)
thank you, most helpful and efficient video ive seen
great video w great elaboration and walk through ! :)
you dont know how much your 8 minutes helped compared to my teachers week thats cause hes using the one that involves using your whole hand
The lecture we all wish we had- thank you sir
Thank you very much sir for the assistance regarding the magnetic force with regard to the right hand rule
some how I have learnt that rule in 3 minutes...brilliant work..cheers
Great video, well detailed explanation.
This was beyond helpful, thank you so much
Nice job, you explained it perfectly!
Thanks for uploading this :3 Finally got it!
Just got barraged with knowledge and actually understood it. Great video. Wish you were my professor.
omg learned in 8 minutes from this video. meanwhile 2 other tutors and the prof and the TA been trying to teach me for 2 weeks now.
This was so helpful. Thank you so much.
From 5:24
The red vector is B, magnetic field strength (since it's a vector it comes with direction. So B, field strength, has information about the magnetic field strength and the direction of the strength)
The blue vector is V, the velocity (another vector).
The pink vector is the force on the positive or negative test charge
This video is extremely helpful. Thanks!
I love this guy so much. Thanks bro.
This was so helpful and quick!!
Physics can be confusing, this video helps make it more understandable. Thanks.
thank you so much you really helped me, 2020 and still helpful♥
I'm watching this video in 2020. It really helps. Tks a lot
This is MCAT gold. THANK YOU!
Sir you just saved my life, thank you sooooooo much!
Thank u so, so, so much. i thought I never would understand this before watching this video
It's 2021 and this video from almost 7 years ago has saved me.
This was the ONLY video that made me understand the right hand rule!!!!
Thank you. I was losing my mind over this, but it finally clicked.
if only my physics teacher taught this easy. I have a test tomorrow and you just saved my life
Really helpful and clear, thank you
Nice video man it's pretty cool listening you
