Your channel just saved my ass! I'm doing a Bsc mechanical with an electronic module which I don't understand, but hopefully I will after a few of your videos
i have some thoughts about the first example, the angle between n (the unit vector n of the normal line as he called it ) and B (the magnatic field ) is 180 degrees which is cos(180 = -1 otherwise it would be the same as the third example where the flux was equal to zero !!!! simply because the flux is an algebraic physical quantity !
What does it mean if the product says magnetic flux is 50 or more? Can it attract more magnets at the same time, like a toy magnetic ball these days? Or is it the power of magnet whose flux is 50 plus? Please accept.
and the graphical representation of the flux density? so is the the AC of the triangle?? so over the Normal? no so it is perpendicular to the surface over the whole area because it is density right?
This is driving me crazy. I checked the settings in my calculator. I plugged in the same info in several websites and I still don't know how are you calculating this because different results. (10)*(0.5*0.5)*cos 40 = 1.915111108. What am I doing wrong?
He did get the 40 degree angle wrong. Looking at it from a conceptual point of view: since the 40 degree angle is more perpendicular to the surface, then it's magnetic Flux has to be bigger than the 60 degree angle
You are correct, but his work is right. He just plugged it into his calculator incorrectly. I did it and I got a larger value, as it should be because it is more perpendicular as you said.
We get it, you Indians and smart. would you please stop fluxing on us estupida peopel hahah get it "fluxing" instead of "flexing" hahah, very clever joke 😎
@@Starrypaws64 Nice one but you misunderstood his joke. In india , calculators are not allowed in classes or exams and if someone uses one in class, it's confiscated.

In the first problem 0.766 is the value of cos(40) . Final answer is 1.9wb
I thought I got the wrong answer after try it for myself
oki doki
yeah
I'd thought so.
I got that too
exam season guys. if it wasn't for this man^^^^ I would not pass college. much thanks!!!
i love you man thanks for always virtually being there for me lolol
Your channel just saved my ass! I'm doing a Bsc mechanical with an electronic module which I don't understand, but hopefully I will after a few of your videos
I got 1.92 Wb for the 40 degree angle not .766
He made a mistake
yes me too
Yes
I thought my calculator was wrong
Me too!!!
thank you organic chemistry it helps me a lot in college😄
😂
so simple and unserstandable. Thank you!
Thanks Mrs knowledge saver, i love you moon and back
you're, undoubtedly, the best.
Indubitably

You are a legend man

simply because the flux is an algebraic physical quantity !
Thanks,I understand what is theta in magnetic flux density ❤️
cos40 degree value is 0.766.But the answer of the question is 1.915
that was my concern either
ur an angel
Thanks again old friend
i keep getting 1.92 wb for the 40 degtree magnetic flux.
Ivonne I’m getting the same thing I think he put the wrong answer for that problem
Ivonne the answer doesn't matter. The way of solving the question only matters.
It would be 2.4 Wb i think so u have used cos(40°) instead of it u have to use cos(50°)= cos(90°-40°)
same
@@nabilmiri128i hope so
Great explanation, thank you
Thank you
What is A
another great video.. do you have one on calculating the distance 100mm to 200mm of a eddy current sensor from steel vs aluminum? thanks a lot...:)
In no.2 ex
Can we say total flux thru plane is zero
Acc to guass law
I got 1.915 for the first of the two last problems
There is a mistake when solving for the first magnetic flux
The answer is 1.915wbm² and not 0.766
I hope i have ur brain 🧠 i had difficulties in solving maths questions . Honestly , I hate maths .
Relatable
Thank u for this
5:53 i think it should be (10)(0.5)^2 cos60
لا !! Cos40 صح ... لازم تاخذ الB مع ال N
Isn't the flux supposed to be negative if it's going into the plane of the surface?
What does it mean if the product says magnetic flux is 50 or more? Can it attract more magnets at the same time, like a toy magnetic ball these days? Or is it the power of magnet whose flux is 50 plus? Please accept.
İt is very difficult. i cant process physic problems beacause physic is so difficult than other lesson.
👍Awesome vido
I feel there is a mistake in the first part of the last example
and the graphical representation of the flux density? so is the the AC of the triangle?? so over the Normal? no so it is perpendicular to the surface over the whole area because it is density right?
Which class is this😵
Cos theta is 90° is first question ... So how the answer is 3.3 wb ..... Magnetic flux should be zero , right ??
Why does cos 90° gone??
.766 is the cos40 not the answer. The answer is 1.92WL
I’m looking at 243. On a scale minus 10. So everyone is better at this than me lol.
There is no way the 60* angle can produce a greater value than the 40* angle.
He got the wrong answer on the first part of the last problem. .766 is cosine of 40 degrees. He forgot to multiply it by (10 x 0.25).
i thought i am the one who got wrong ans, lol. the answer is 1.92Wb
saviour
The last 2 problems could be a mistake
This is driving me crazy. I checked the settings in my calculator. I plugged in the same info in several websites and I still don't know how are you calculating this because different results. (10)*(0.5*0.5)*cos 40 = 1.915111108. What am I doing wrong?
nothing wrong he made a mistake
Is it fata or data? Simetimes i hear you say fata sometimes i hear data. Which is it?
It's neither. It's actually 'theta' [pronounced "thay-tah"]
I got 1.92
Big mistake near 5:10
He didn't calculate the whole answer , he accidentally put the value of cos40 in there lol
then what's the answer?
1.91 Wb right?
@@yeahah8036 that's what I got
The first answer should be in minus...
isnt 10cm x 10cm = 1m not 0.1m?
He did get the 40 degree angle wrong. Looking at it from a conceptual point of view: since the 40 degree angle is more perpendicular to the surface, then it's magnetic Flux has to be bigger than the 60 degree angle
I agree
You are correct, but his work is right. He just plugged it into his calculator incorrectly. I did it and I got a larger value, as it should be because it is more perpendicular as you said.
ما اقول الا الله يهديك للاسلام
Getting really lost at 3:149264. Just lost. Lol
its not thada its thieter
why do you even care about values
2.4 Wb for 40 degree
hey man are u married because if not i will propose to u right here right now
Men can you show us your face..hahaha ,,
seriously using calculator.......in india it would make everyone lol 😂😉
We get it, you Indians and smart. would you please stop fluxing on us estupida peopel
hahah get it "fluxing" instead of "flexing" hahah, very clever joke 😎
