Hi everyone.
I just created a YouTube video explaining all the basic concepts of
electricity and magnetism.
It is available at
http://youtu.be/XiHVe8U5PhU
I put a lot of time and effort into making this, so I hope you like
it.
Please pass this along people who you think might be interested.
Thanks.

Cute! One of the better "head banger" videos I have seen. And I think I have
sometimes heard those electrons clanking into each other like a multi-car
pile-up at a roadblock.
I think you have a repeated segment around 6:25, and again at 9:30.

Mostly me and my dog, but some are about electricity and magnetism:

Hi Eugene, Very nice. I have two nit-picky comments.
1.) Somewhere around six minutes you say that magnetic fields exert a
force on another magnet. If fact it is the magnetic field *gradient*
that exerts the force. A magnet in a uniform magnetic field feels
only a torque.
2.) At the end with your E-M waves you have the E-field creating the B-
field and then back again. This is true in the near field, but in the
far field the E and B fields are in phase.

That's why my time machine doesn't work. How do I get the far field
out of phase? and what if any impact does it have on anything?
enlighten me please.

No in the far-field the E and B are in phase.
(It's just something I'm sensitive too.)
I use to (maybe 15 years ago) have this picture of E-M waves as being
like an oscillator. (Think LC if you like) With the energy sloshing
back and forth between E and B fields. Someone pointed out my mistake
and I spent a few days 'adjusting my outlook'. I don't have a good
physical model of why they end up in phase. (Except that's what falls
out of Maxwells equations.)
I'm sorry that's all the enlightenment I have, I still find E-M waves
a bit puzzling. Like that they don't experience time, that's baffling
to me.
