ngl, favorite parts of his teaching style is the way he'll say, "so what would that look like???" and then the immediate follow up is a sick diagram and a clean ahh explanation of what's being shown it's like boom... I get it. Other profs say shit like "so what does this mean???" and then they'll try to tell you what it means but make it even more confusing like bruh THIS is how you get information across. (i'm a highly visual learner if you couldn't tell.)
Would be amazing if all Faculty Professors taught like you. Gonna have an eletromagnetism exam next week and your videos are saving my semestre thank you!
I just want to thank you for the quality of your videos. I love the way you explain concepts so easily and make them clear. I know you may not have enough support, but keep it up; you will get what you deserve.
0:56 if you didnt understand what he meant by "B field pierced through a certain area" its like saying "a needle passing through a woolen cloth" as in like penetrating
Hi first of all you're absolutely saving me right now your ultimate reviews are awesome, so thank you so much! Could you please explain why at 22:40 you replaced r with y instead of D? Cus the distance between them is D, and Y having a dy sort of implied that the distance between them was changing. Also, how come B depends on Y when Y doesn't actually have anything to do with area cus it's just used as distance instead of r? In fact why is area relevant at all if it's just the current that is changing? Your help is appreciated :D
So r is the distance from the bottom wire creating the magnetic field. It gets weaker and weaker the further you go. But the way I oriented that wire the r direction is upwards which is the y direction. Just easier to think about as x and y in my opinion so I changed the r variable to call it y, but both r and y here stand for distance vertically above the bottom current carrying wire.
@@WeAreShowboat tysm for responding, I appreciate it. I still don’t get why we didn’t take D or why Y is changing, both the wire and square are fixed in place no? Also the last part about the current being the only thing changing so why is area making a difference?
@@nadeenmohiar6193 Magnetic field Abbie a function of y, so when integrating, you have to take into account that the B has smaller values the farther away you go from the wire
@@WeAreShowboat I see, thanks. And if there was a battery so that a current flows through the bar, then you would have to substract the emf created by the moving bar from the potential of the battery, right? In order to not get a ln(0)
but a changing flux is not the causative for the emf, it's only a mathematical convenience. what if B changes non-uniformly while keeping the net flux the same during a period?
Faraday's Law is not a law, just math. In the second and third cases, the emf is motional emf due to the motion of the conductor through the magnetic field and is not due to the changing flux linking the circuit. It is a case of correlation, not causation.

this is the best physics education i have ever seen
It is insane how you explain concepts in such clarity many many thanks!
30:20 that separate integrate celebrate line is too good, imma use it from now on 😂
Best physics explainations out there 100%
This guy is absolutely amazing. He makes everything engaging, clear, and fun to learn, you really can't ask for much more. Thank you!
You are a great teacher, these videos helped me pass Physics 2. Thanks!
The way you personify these concepts and variables is hilarious . Great lecture btw!
"Separate, integrate, celebrate" - amen! Thanks for an amazing video!

Reject solar flux analogy, Embrace SpongeBob. Good stuff man. All your vids have been helping a lot.
Best physics channel I have ever seen.
"These might look hard" me-ok
Best videos ever❤️😩 thank you so much 🙏🏻
These videos are awesome - thanks!
Best exam prep thank you so much holyy
This is amazing. Thank you for this!
On everything u the best teacher
My guy you are such a legend
always the best! thank you
Great explanation/teaching man Keep it up
always great videos
Thank-you bro, you helped me out a lot.
8:50 keep in mind, changing in terms of angle would mean dA = rDrDtheta which means integrating first for R then for angle
Love this review. My physics lecturer is hopeless at explaining, and my tutor doesn't answer my emails, so these kinds of videos really help out.
Love you SIr.
0:56 if you didnt understand what he meant by "B field pierced through a certain area" its like saying "a needle passing through a woolen cloth" as in like penetrating
Thank you for this video.
this is definitely one of the physics video ever
I’m paying tuition and studying online and passing 😂. Thank you so much
you are amazing !!!
Thank you so much!
e &m has been a breeze after i found these vids!
the 3d diagrams help so much
straight goated
Great video 🔥
very good explanations
thank you
ur the goat
Thank you!

@@WeAreShowboat Okay thank you for taking the time to answer me🤍
you save my ass
you are awesome
i really do be carin bout those volts tho 😳😩
LOVELY
i love u bro
you saying b gets annihilated at 17:07 is killing me
What do i use separate, integrate and celebrate ??
It’s a technique for solving differential equations called “separation of variables”
what does variable c equate to ?
I was thinking the same thing, he never explained it
yo shoutout u gang
What does "flux" mean in physics?
Amount of field that passes through an area
What happens if the initial velocity is 0? 30:35
Then the rod doesn’t move and just sits there. v=0 forever in that case
@@WeAreShowboat I see, thanks. And if there was a battery so that a current flows through the bar, then you would have to substract the emf created by the moving bar from the potential of the battery, right? In order to not get a ln(0)
@@mathiasr27 Yeah, with a battery it should start moving until back emf equals battery voltage when it moves with constant velocity
@@WeAreShowboat thank you
Can we download those pdfs somewhere.
There’s a link in the description under the video
i love u
