@@jacobvandijk6525 Yes. It usually is. For example it's not impossible to derive e = mc² quickly & mathematically in YT videos. However, 95% of teachers are not able to do it. They simply do not have the skill that DrPhysicsA has. The ones that try don't get many views because their videos are confusing & unsuccessful. Great teachers are like gems I found some other things that have gem-like properties: 1) A book: Engineering Mathematics by Stroud - very gentle & clear with many questions & problems to work through 2) Supermemo software uses flashcards to make it almost impossible to forget the stuff we learn 3) Meditation on compassion & loving-heartedness.

At school, we were given a copy of George Gamows Biography of Physics to read. I was bowled over by the story of James Maxwell showing mathematically that radio waves are emitted by an oscillating charge and that he had calculated the velocity of these waves and it was the same as the velocity of light. I think it was this that enthused me to do a degree in Physics, along with Special Relativity. Unfortunately, my maths wasn't up to the task, so I changed to a Mechanical Engineering degree, but I have always regarded Maxwells equations with awe. I now understand them, at seventy-seven years of age. Got there eventually.

re: magnet partly inside the sphere (18:23): Even then the equations still hold. The magnetic flux outside of the magnet goes from the north pole to the south pole. Inside the magnet the flux always goes (back) from the south pole to the north pole. If the magnet is placed such that only the north pole is inside the sphere the amount of flux exiting and entering the sphere is still equal: the same amount of flux going from the north pole, out of the sphere to the south pole is going inside the magnet from the south pole, entering the sphere to the north pole.

19:00 I agree with Pablo P, the magnetic field lines travel through the bar magnet. So although they don't spread out like they would at the edge of the south pole, there is just as many magnetic field lines passing through the midpoint of the magnet as there are field lines exiting the norht point. Not suggesting Dr Physics is wrong, just that there are different ways to look at this and I hope it helps others to consider this from different angles.

Very nice explanation. TY.
Truly brilliant! Thank you very much!
As someone who saw this 2 years ago in college and needs none of it in my faculty (civil engineering) I can say this was pretty neat. I thought I'd never unverstand Maxwell's equations. At this moment I understand 100% of the 1st equation.

dan iel I was just thinking the same thing. I couldn't even remember more than one definition out of every two hour Chem class.. and that in the tenth grade. Hahaha i and I'm 25 and can't believe how beautiful it is now. New favorite subscription!
This video helped me a lot....Because I am not good in electrostatic and this helped to make my base strong for PGRE entrance.
Great explanation! Thank you 😊
re: magnet partly inside the sphere (18:23): Even then the equations still hold. The magnetic flux outside of the magnet goes from the north pole to the south pole. Inside the magnet the flux always goes (back) from the south pole to the north pole. If the magnet is placed such that only the north pole is inside the sphere the amount of flux exiting and entering the sphere is still equal: the same amount of flux going from the north pole, out of the sphere to the south pole is going inside the magnet from the south pole, entering the sphere to the north pole.
Amazing video. Just thanks you so much.
awesome stuff, really clarifies a lot!
Superb. Just what I was looking for.
This is an awesome video. Thank you.
Your video have helped me a lot in physics
19:00 I agree with Pablo P, the magnetic field lines travel through the bar magnet. So although they don't spread out like they would at the edge of the south pole, there is just as many magnetic field lines passing through the midpoint of the magnet as there are field lines exiting the norht point. Not suggesting Dr Physics is wrong, just that there are different ways to look at this and I hope it helps others to consider this from different angles.

Thanks. Very kind of you to say so.
Best video i have seen on utub so far
My English is no that good , but I really understood this better than my teacher who is explaining in my language ! Thank you for using simple English words :)
Wonderful... U r God sent
I love how physics handle infinitesimals. Anyway🖤, beautiful explanation🔥
So nice and educative sir
Many thanks from Maxwelltown Dumfries
