Let's solve problems on finding the direction of the force on a moving charge in a magnetic field. We will use Fleming's left-hand rule for this. Created by Mahesh Shenoy
Well, what's better than a cheat sheet of rules in your own hand. just move it and you know the answer. Otherwise, you could just remember it and imagine in your head
According to the 3rd law the force will have a equal and opposite reaction right..? Then both of those will be cancelled out thus making the force on wire equal to zero.. Please help me here...!!!
The magnetic field we consider is not of the conductor, it is of the magnet. Right hand thumb rule derives relation between magnetic field of a conductor and the current flowing through that conductor.
See the whole magnetic field is drawn in perspective of North Pole so the inward direction at South Pole is the direction in which the North Pole would react so the South Pole would react the opposite of North Pole
According to the magnetic field, if there was a north pole there, it would have experienced a force into the screen but as you know there is a south pole so it experienced out of the screen.
If it was a north pole over there, it would point into the screen because if we put a compass in that position, the north pole of the compass would point into the screen, but in this case there's a south pole instead of a north pole so when we put a compass there, the south pole of the compass would point out of the screen. Thus explaining why the south pole experienced a force into the screen.
See the way the arrows point,the north pole experiences a force into the screen,so where should the south pole point..? Btw coincidentally we've got the same name,I'm Arshia here😁
i cramped my hand in the exam hall, thanks fleming
Deriving the directions from newton's 3rd law is easier than doing this fingerplay sorcery
frfr
Please what's the tip
I like how you put Fleming's left hand rule as some kind of fingerplay sorcery XD
Real.
Can someone please explain how to use the 3rd law in this case. I can't understand it.
How well have u explained the reason behind the left hand rule! Awesome! This channel is of another level.
Lol We learned it as
Father ( force)
Mother ( magnetic field)
Child ( current )
mahesh shenoy my fav
absolutely amazing now I'll tell my friends also bout this
Sir u have a very nice voice
Oh, so I'm not the only one who thought that!! 🤭
😍loved the concept very well
Thank you, amazing explanation.
That looks and sounded painful
I loved this video.thank god for khan academy
Can't we have better way than the Fleming's left hand rule!
I know right it sucks
Sorry because it is the only best way to find the direction of force easily what can we do we have to expect it ...and try it..
it is easy
Well, what's better than a cheat sheet of rules in your own hand. just move it and you know the answer. Otherwise, you could just remember it and imagine in your head
Go make your own way...I don't think there's an easier one 😂
right hand palm rule
Very Nice 👍😊
Good work
Concept cleared
Is the Force direction described an attraction force or repellling force?
Thankyousomuch sir!
This video made me realize that I never ever moved/stretched my left hand fingers😂
PS:Yeah It's paining ....lol
According to the 3rd law the force will have a equal and opposite reaction right..? Then both of those will be cancelled out thus making the force on wire equal to zero.. Please help me here...!!!
when u walk up to a 10/10 in club and trow these gang signs
Nice hands
🤦🏻♀️🤦🏻♀️🤦🏻♀️🤦🏻♀️🤦🏻♀️
I used to remember it as IBM
I for Current
B for mangectic field
M for motion or force
BMI
Gud video
Sir how did you make all those drawings. Is there any app
❤️
At 9:25, but from the right thumb rule,it can't happen right,how can there be an angle lesser than 90 between the magnetic field and current...?
The magnetic field we consider is not of the conductor, it is of the magnet.
Right hand thumb rule derives relation between magnetic field of a conductor and the current flowing through that conductor.
Anything
Force goes in
4:12 I didn't understand why the South pole didn't experience a force into the screen, and why out of the screen. Please explain Sir
See the whole magnetic field is drawn in perspective of North Pole so the inward direction at South Pole is the direction in which the North Pole would react so the South Pole would react the opposite of North Pole
According to the magnetic field, if there was a north pole there, it would have experienced a force into the screen but as you know there is a south pole so it experienced out of the screen.
See his previous lectures about magnetic field
If it was a north pole over there, it would point into the screen because if we put a compass in that position, the north pole of the compass would point into the screen, but in this case there's a south pole instead of a north pole so when we put a compass there, the south pole of the compass would point out of the screen.

Why does a wire carrying the current produces magnetic field?
Bcz, movement of electron I think so
Idk...it's because whenever there's an electric field,there'salways a magnetic field, it's proven using an experiment,though.
FBI lol
die for uu
I did not understand
Low iq😂😂😂
Such a complicated explanation😑
Sir try to speak a little fast just a suggestion
2X 3X 4X
no its ok
I think this speed is perfect so that those who are a bit could also cope up
You can adjust the speed by clicking playback speed by clicking the three dots .
