7.5.2 Poynting's Theorem

[@woof.woof.]

I appreciate you explaining it in more detail than the book. Thanks!

Thanks, be sure to share these videos with your friends. It helps a TON in promoting my channel.

if delS>0 d(Um+Uem)/dt

[@numbo655]

Why is dW/dt the total work? What happens in the transition at 3:45 where you put an integral on the right hand side and set dW/dt on the left? Seems to make no sense?

[@danieledefrancesco2607]

It's written wrong. You should write F = q(E + (v x B)) and then q = integral(Rho dv)

Thank you!
at 15:40 there's a negative sign besides the divergence of S.

2:55 magnetic field does not work you said,why please? is'nt it we have magnetic field and electric field?

[@ag_008]

Work done by magnetic field on a charged particle is zero

[@alictg81]

Tarik HADDAR you can get it mathematically as well, v cross B always lie on the plane perpendicular to v. Dot of v with a vector perpendicular to it is zero.

[@tuckerhartland1001]

Same reason as you had for the minus sign on divJ=-d rho/dt

Great job, very thorough. All I could think about was how much my hand would be hurting, haha.

The clock ticks in the background are driving me insane…
Thanks for the video, though. Really helpful.

[@lazyaditya1990]

Thank you, it really cleared my doubt.

Again jonathan sr you rocked the topic so helpful sr from india🎊🎄😃

[@lameitout]

I hate the sound of that marking pen rubbing on the paper... Really trying to resist. What's wrong with me?

[@jg394]

It bothers me too. I wish I had a solution. Could be worse-chalk grates me.

[@lameitout]

​@@jg394 Funny thing is, I can stand chalk on the board a little, but not pencil or mark pen. Every time I try to use mark pen, once I hear this 'tizz' sound, I couldn't even hold the pen in my hand, and it is shaking. Thank god we have computer animation.
