Magnetic Force on a Current Carrying Wire
ฝัง
- เผยแพร่เมื่อ 17 ธ.ค. 2017
- This physics video tutorial explains how to calculate the magnetic force on a current carrying wire in a magnetic field. The magnetic force depends on the current flowing through the conductor, the length of the wire, and the strength of the magnetic field as well as the orientiation of the magnetic field relative to the conductor. This video also explains how to determine the direction of the magnetic force on a current carrying conductor using the right hand rule and the i j k technique. This video on magnetism contains plenty of examples and practice problems.

I don't know who you are ...but for me, you are like a magician...who have all the solutions to my problems...
Hats off to your techniques....
thank you from the core of my heart.
You are AMAZING!!!... I never really saw how you calculated the Cross products of the i,j,k Vectors.. but you made it so clear!!. THANK YOU.. and by the way..how do you know SO MUCH about everything????.. Math, chemistry, Physics..... what is your degree in???.. wow.. you are so good at TEACHING all these concepts with so many examples!! You bring a Great service to the WORLD!! thank you!!
If you point with your fingers in the direction of the Current (I) and curl your fingers towards the magnetic field (B), your thumb will be in the direction of the force. Thought I would post this for anyone who may find this easier to comprehend.
Kaleb D. Correct.
Thanks a lot!!!
Thanks ra 😊
This hand rule always confuses me. They say right hand but they’re showing a left hand most the time
@@enriqueg5556 don't use this rule. its garbage for this and more useful for vectors
use the left hand FBI rule instead, with your thumb, index and middle finger all perpendicular to each other like an xyz coordinate plane
I - current direction, middle finger
B - field direction, index finger
F - force, thumb
Since you are determining the Force, you need the Left Hand Rule (motors - Right H Rule is for generators). Therefore, Center Finger towards current, First Finger towards field => Thumb gives direction of force.
You are a super human with extraordinary powers! Thank you again!!
I was really confused when my exam tells me only the direction of magnetic field but now i know the direction of the force and the velocity. Thank You Man.
In this particular topic I felt as if I was bumping into a brick wall. However, now I'm very clear and have fair understanding.
🙏🙏
thank you again! also we can use the left-hand rule to find the direction the force: let the B go through your palm and four fingers point the direction of I, then the thumb will point to the F :)
Thanks !! :D That's the method we learnt in China mainland though I didn't quite get it LOL
Thank you so much!!!
thank you for this!
You are the best
thank you
Thanks bro💯💯
Thank you again
Why is it that you are saying we use the right hand rule but you drew a left hand
I can't understand..
thanks
Thank uuu
What if the B value is given but amps and length is given? How am I supposed to find out the magnitude of the force
isnt it actually a combination of two magnetic fields ?
Thumb in direction of current (I)
Four fingers in firection of mangentic field (B)
The flemings left hand rule does not work in these examples right ?
no you can use left hand rule
what if we have the direction of the force and current but we need to find the direction of the magnetic field? what will we do then? huh?
Why do you have to change to meters from cm
When you multiply (current)(length)(magnetic field) the units are:
(A) (m) (kg/A*s^2). So your amps cancel and you're left with kg*m/s^2 which is the units of a Newton, which so happens to be the units of FsubB.
Both techniques were awesome but sin 0 degree is zero not 1
How tf you find the direction of the magentic force at 13:51??? bro i almost broke my hand and i still couldnt do it !!
"sin of zero is one"
-Organic Chemistry Tutor 2017
sin 90 =1, sin 0=0
So human in TH-cam videos are not allowed to make minor mistakes????
I think you get the point smartass, move on
I use both techniques lol!
Sin 0 is 0,cos 0 is 1.Pls correct that sir.
This dude is straight hacking
For anybody that didn't understand the right hand rule, since it's hard to showcase it on a piece of paper: th-cam.com/video/bM738MUY-NM/w-d-xo.html

19:19 sin0 is 1, ye ye
why is sin teta 90 instead of 45

phuck im failing physics chemistry maths and stuff, pleaser help me organic chemistruy tutor. Im from australia and can i please send you my homework assignment, and can you please help me?
