Magnetic Flux, Basic Introduction - Physics Problems

This physics video tutorial provides a basic introduction into magnetic flux. The magnetic flux is the product of the area of a surface and the component of the magnetic field that is perpendicular to the surface. This video explains how to calculate the magnetic flux passes through a square and circular surface.

In the first problem 0.766 is the value of cos(40) . Final answer is 1.9wb

[mariofox]

I got 1.92 Wb for the 40 degree angle not .766

[unholykraut]

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

[شوقالرجيعي]

i love you man thanks for always virtually being there for me lolol

[adamgarcia]

exam season guys. if it wasn't for this man^^^^ I would not pass college. much thanks!!!

[cedrixsumande]

thank you organic chemistry it helps me a lot in college😄

[dinmukhamedarzhan]

so simple and unserstandable. Thank you!

[Ivonnep]

i keep getting 1.92 wb for the 40 degtree magnetic flux.

[umeshchandra]

Thanks, I understand what is theta in magnetic flux density ❤️

[turkishandmore]

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 !

[thinkitfirst]

cos40 degree value is 0.766.But the answer of the question is 1.915

[qzorn]

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...:)

[Exachad]

Isn't the flux supposed to be negative if it's going into the plane of the surface?

[peterpaul]

There is a mistake when solving for the first magnetic flux
The answer is 1.915wbm² and not 0.766

[kazimimam]

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.

[ayaz_yt]

In no.2 ex
Can we say total flux thru plane is zero
Acc to guass law

[puiebhm]

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?

[aymanahmed]

5:53 i think it should be (10)(0.5)^2 cos60

[shiv]

Cos theta is 90° is first question ... So how the answer is 3.3 wb Magnetic flux should be zero, right ??

[melvynng]

I hope i have ur brain 🧠 i had difficulties in solving maths questions . Honestly, I hate maths .
