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:
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.
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
@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
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!
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!
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.
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
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.
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.
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.
as he says earlier, when you see an "x" or a "+" inside each circle, this means the field is going away from you. when the circles have dots, the field is going towards you
When we were in high school in nineties, our physics teacher taught us the "thumb, rest of the fingers and palm" method; in which you open your right hand thumb in one direction showing the movement direction, four fingers the direction of magnetic field and imaginery line going out of the palm shows the force to a positive charged particle(if moving particle is negative, opposite of the palm is the direction of the force). I have always found that more convenient! With that method, you dont have to put your wrist in some weird positions to figure out the directions
As far as I know, the right hand should be magnetic force on the thumb, magnetic flux on the first finger and current (I.e velocity of the charged particle) on the middle finger. How come it's the opposite for the first and second fingers at 3:24?
The way you wrote them is for the left hand. Using the right hand you have to use the middle finger for the magnetic field and the index for current (velocity of positive charge) . For negative charge you flip the result or use the other hand. . Stick to one rule but keep in mind which fingers are which vectors for each hand. . Again Left hand rule for positive charge is Thumb = Force Index = magnetic field Middle finger = velocity of the positive charge . Right hand rule for positive charge: Thumb = Force Index = velocity of the positive charge Middle finger = magnetic field
You flip if it's an electron. It's not about convention, it's about the charge of the particle regardless of what you consider the direction of the "current".
Imagine taking the AP test only for the supervisors to shut it down because they think you are trying to communicate with the other students when you are using the right-hand rule.
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.
Thank you for explaining the hand rules so clearly, I completely didn't get them at first, so I think I flipped the bird accidentally a lot of times during class!
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!
Youssof Zayed use left hand 1.index for Magnetic field. 2.middle finger for velocity. 3.thumb for force. and for a negative charge just use right hand.
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.
3:15 "You might look like an idiot as you're doing that, but it's worth it" xD 5:35 The animation on the left is too fast. Plase, note for future videos to make such animations slower.
You know what’s funny , I feel videos like this and tv shows on science are much better at educating for one reason , they rely on viewership for the video/show’s success. They make much more of an effort making sure you understand it then most textbooks , because physics in education doesn’t rely on people passing , and as for taking the class you have to take it so they don’t rely on people taking the class for the success of the class (payday). The language in my textbook complicates this so much it is actually unbelievable . Just some thoughts I had, thank you good sir.
Well to your credit, UNDERSTANDING the concepts, and how exactly things behave is exactly what is expected of you. The math is NOT that hard. What IS hard in a question is trying to figure out WHAT KIND OF MATH TO DO BASED ON THE INFO
Safwan Hossain Yup... ....and that understanding requires practical application examples that are relevant to our interests so that we are able to recall the methodology when we encounter circumstances where we need it. Without that application we forget all of this stuff we learned in school and we're stuck twiddling our thumbs to AdSense commercials on here. It's a Google conspiracy ;))
remirez avante I was taught just like you. in the left hand rule, which you know, has FBI. Thumb representing the force, index finger representing the magnetic field (North to South) and middle finger representing the CURRENT.
I may be wrong but i think it's very important to emphasize that when we be dealing with electron which has a negative charge, we should mandatory use the left hand. As the professor said you can also use your right hand as long as you turn the force around when you're done but to me, you should just use the most "accurate hand" for each particle.

LEFT HAND RULE!
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.
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

Why you seem to be expert in all all the academic subjects? Such a genius....

agreed
You are my hero! I can always count on Mr. Andersen to explain what others can't. Thank you.
I absolutely love physics - but it honestly gives me such a headache...irritating. lol
I love how concise this video is. I'm just reviewing for My MCAT. Thanks!
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!
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.

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.
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.😂

QUESTION: AT 4:24, WHY IS THE MAGNETIC FIED "NOT COMING TOWARDS US" AND WE HAVE TO FLIP OUR HAND ?
as he says earlier, when you see an "x" or a "+" inside each circle, this means the field is going away from you. when the circles have dots, the field is going towards you
When we were in high school in nineties, our physics teacher taught us the "thumb, rest of the fingers and palm" method; in which you open your right hand thumb in one direction showing the movement direction, four fingers the direction of magnetic field and imaginery line going out of the palm shows the force to a positive charged particle(if moving particle is negative, opposite of the palm is the direction of the force).

As far as I know, the right hand should be magnetic force on the thumb, magnetic flux on the first finger and current (I.e velocity of the charged particle) on the middle finger. How come it's the opposite for the first and second fingers at 3:24?
Yes! Please help
The way you wrote them is for the left hand.
Using the right hand you have to use the middle finger for the magnetic field and the index for current (velocity of positive charge)
.
For negative charge you flip the result or use the other hand.
.
Stick to one rule but keep in mind which fingers are which vectors for each hand.
.
Again Left hand rule for positive charge is
Thumb = Force
Index = magnetic field
Middle finger = velocity of the positive charge
.
Right hand rule for positive charge:
Thumb = Force
Index = velocity of the positive charge
Middle finger = magnetic field
This explanation was awesome. Going to ace my physics test now! Thank you

LEFT HAND RULE
Thank you! This makes understanding the "right hand rule" so much easier than my professor and my textbook.
5:00 should the force be on the right instead?
raptor theok Exactly
+raptor theok no because it is a electron, you flip the right hand rule force or use your left hand
It depends....
Due to conventional and true current.....
ohh okay makes a bit of sense
You flip if it's an electron. It's not about convention, it's about the charge of the particle regardless of what you consider the direction of the "current".
This was the ONLY video that made me understand the right hand rule!!!!
Imagine taking the AP test only for the supervisors to shut it down because they think you are trying to communicate with the other students when you are using the right-hand rule.
