Could you explain (in an intuitive way) why "constant current induces constant magnetic field, but only changing magnetic flux induces current"? Since electric field and magnetic field are intrinsically only one thing, why constant magnetic field does not induce electric field but the reverse?
There is something that I'm not quite grasping here. It is understood that magnetic Flux is stagnant on its own, and yet it is described as going into or out of a given area going in or out implies movement . These are verbs/action words. Flux does not move unless one moves it. What is actually meant by The flux lines, 'B field' is going in or out?
wait I took in my class that the magnetic flux is at maximum when field lines are PERPENDICULAR, therefore sin(theta) is used not cos(theta); can someone elaborate?
Correct terminology is about the surface vector. This is the vector the area is facing. Hence flux is maximum when cos theta equals one. What do you have been taught is the direction of the plane versus the direction of the magnetic field. so at maximum flux the angle is now 90°. So, what you have been taught will give you the same answer, better physics terminology refers to the surface vector.
@fatimahadi3845 Think of the surface vector as the normal to the surface. Since flux is the number of field lines passing through the surface then this is at a maximum when the field vectors are parallel to this normal. The angle is zero at this point. This means cos0 thus = 1. Similarly if the field lines run across the surface then these very field lines are perpendicular to the normal (surface vector). Flux is 0 since cos90 = 0
"20 magnetic field lines" a quanty of imaginary things? I get using the concept of field lines to visually represent field direction and line density to represent field strength. But when were not careful, way too many people end up dumber then when we started. Field lines are not real. Somehow, some people end up thinking 1) they flow, 2) or that there are magnetic vortices and ferocells are proof of it. 3) Or dont understand why homopolor generator spining a magnet on its pole doesn't spin the magnetic field lines (that dont exist), but if you spin a conductive plate about a magnetic pole, it generates an emf between the inner radius and outer radiuss of the faraday disk.
I am glad to watch this father's video thank you please if you are non-muslim safe yourself from helfire and follow the commandment of the last and final messenger prophet Muhammad p.p.h.m Christ is the only messenger of Allah that his followers misunderstood him,but he never claimed divinity this universe is test life but it's not eternal life please watch Dr.zakir naik similarities between the islam and Christianity ❤❤
Been checking for a while a video that explains this concept and this one is the best one yet - thank you !
Great to hear!
I've been surfing for hours and this video explains it so simply, with intuitive visuals to go along with it.
well done and thank you very much!
As a Masters Student in EE, this is really amazing review!
First video I watched to understand magnetic flux and so glad I did. Thank you! You explained it so well and I understand now!
Glad it helped!
Brilliant video! Free content of this quality brings me joy!
Watched many videos but ended up here understanding every concept .
thank you so much sir , really appreciate you
Simply great, You make fluxes visible, Sir.
Certainly best videos about this subject too.Congrulations
Flux means "flow." The units of water flow are volume divided by time.
So what is the meaning of the term "flow of magnetic flux"?
Isn't necessarily volume sometimes its mass pretty much any unit divided by time (dotted)
thanks for the great explaining, sir! i've been struggling for almost half an hour, and you made it so easy to understand!
Love the props you used. Really clear explanation, thx
Nicely explained!
Great video, nicely done. Please keep them coming.
Cheers
Mate, this was great, awesome visualisation
Thanks a lot!
Best video on this topic, thank you so much!
Where do you want your coffee,two sugars four creams?
🤣. Two and cream please

Thanks sir for the clear explanation of how the formula came.
There is something that I'm not quite grasping here. It is understood that magnetic Flux is stagnant on its own, and yet it is described as going into or out of a given area going in or out implies movement . These are verbs/action words.

The coil is rotating causing the magnetic flux to enter and exit as it rotates.
Thank you for simplifying this concept for me! It is really hard to find concise videos explaining physics topics!
Awesom! Priceless!!!
Thank you!
You're the bomb Paul
Thanks
Bravo bro!
Thanks a lot!
i love how his shirt represents the feynman diagram
this guy saved my grade
Thank you ❤❤❤
excellent

oh alright, but i am still skeptical about the cos, because if the vector is parallel then it won't intersect the field @@PhysicsHigh
@fatimahadi3845
Think of the surface vector as the normal to the surface.
Since flux is the number of field lines passing through the surface then this is at a maximum when the field vectors are parallel to this normal. The angle is zero at this point. This means cos0 thus = 1. Similarly if the field lines run across the surface then these very field lines are perpendicular to the normal (surface vector). Flux is 0 since cos90 = 0
2:09 that damn symbol is EVERYWHERE
Thanks sir❤
omg thank you so much
than you sir 😭😭😭
