"because if you did that it, it would just keep flipping over, which I don't know.. could be useful if you wanted to.. flip things."
hahahaha I'm sitting here in the library laughing out loud watching physics videos... only you Sal. You're potentially the only reason I'm going to pass this class.
Cant you just use an AC supply or is it not possible since if the rotation gets faster it wont be possible and you cant have variable frequency of AC?
Ok, to those who think the video is wrong, well, not, you guys are. The whole video is right. If you doubt then just watch again and again until you figure it out. If he was wrong, you would not be able to watch this videos on an electric computer.
I don't really get why there would be any angular momentum left,shouldn't it amount to zero by the time the coil has taken up the latest conformation???
6:34 – yes it is. I think that it’s, inspirational that one can learn how an electric motor works, for free, after studying I’d say about just 5 hours of videos. Thanks Sal, I appreciate what you’re doing.
I believe the arrows in purple and orange are pointing at the wrong directions, isn't (x) supposed to go into the screen and (o) supposed to come out of the screen at our direction?
@hbejgel2 yes!!! me too, it seems to me that (x) is supposed to go into the screen and (o) supposed to come out of the screen, and not the sens of rotation that he draws in this video!!!
I've been studying magnetism at school for 3 weeks? The concepts are so vivid and hard to understand, exspecially for a Dc motor. You've managed to make me visualise these concepts, thanks so much.

isn´t it easier if the battery just spins too? :p
oh... nvm... i wish wires could just spin allover :D

I just jumped right to this video. It looks like a vacume cleaner I took apart on time.
