Videos do NOT get any better than this one!!! Excellent from Beginning to End... BEHOLD THE POWER!! Power to the PEOPLE.. :D .. Thanks Doc Schuster!! :)
At 5:05 did you mean to say that the induced voltage is an Electric field? You said one thing and wrote another, I'm confused. Could you please clarify Doc.
IbanezV70CE I think I totally did. I had to watch that five times to figure out what I may have meant. Thanks for the tip - I put a note in the video to correct my error.
+Strobe Lala Well, careful! This is the most important part to get here. The potential difference is developed across the moving bar in this situation, so that's where a linear electric field is present.
Second question (maybe more to come hopefully mahyaps):: focusing: how do we know what the direction of the length of the moving wire is? (I'm trying to figure it out so that I can do L x B in the BIL equation to find the direction of the force on the moving wire tHX :;:DDD
+Strobe Lala I like to think of it exactly as qvB and do v x B. The velocity of the wire is to the right. It feels weird to say that the length is to the right, though.
+Doc Schuster Doc, Thank you your excellent video. I have been searching Google for any explanation how mechanical power is equivalent to electrical power. And your derivation of equations makes the most sense. Pleas help me understand a few more things here. From electric car's point of view it is well said that 746 watt is equivalent to 1 HP. Electric power and mechanical power use equivalent units but they are not equal so to speak (is this true?) I mean falling down onto floor(mechanical) is certainly different than getting shocked(electrical). I understand that 746 mechanical watt is defined as 1HP. But can 746 electric watt perform equivalent of 746 mechanical work? How? (Is it similar to your pushing rod analogy to how the electric motors create mechanical work?). I can live with the statement that 746 watt is just defined as 1 HP for convenience's sake, fine. If we hypothetically assume an electric motor has 100% efficiency, and if 746 electric watt is used can I expect 746 mechanical work to be output?
I watch these videos a lot they help me focus

i love this guy
thank you so much for great videos!

Why is the distance in the V=-Ed equation the length of the wire?!? ;** U ROCK DOC as previously mentioned
+Strobe Lala Well, careful! This is the most important part to get here. The potential difference is developed across the moving bar in this situation, so that's where a linear electric field is present.
+Doc Schuster third question: why does a CHANGE in flux create a current/ Vinduced thxxxx ;))))
as the resistance goes to zeros, shouldnt it be impossible to push the bar, since the magnetic force on the the charges becomes super large?

generator is that the same principle for the energy power stations
So wait a second. your saying that this (theoretically) should be a generator with 100% efficiency?
+F!@#Guilt Yessir, that I am.
