What happens when you pull a wire loop through a constant magnetic field? There is an emf generated. What does the work to push the current through the resistor?

I was wowed by the wedge pushing the ball explanation. damn you make electrodynamics readable for me. 🛐
Thank you a lot!!
Thank you sir i watch your lactures and learn to much from it.plz do the compleate cource.agan thank you very much
So if I need to calculate my coils voltage, where a segment of the coil is passing through a magnetic field, I would use v x B x (5 x h) = Volts
v = Linear Velocity converted from Radial Velocity, meters
B = Strength of the magnetic field in Teslas
5 = Number of turns
h = segment of wire which cuts through magnetic field, length in meters
Is this correct?
If the magnetic field size stays constant and the coil is larger than the magnetic field, then changing the size of the coil will only change the current in proportion to resistance?
Can we apply this formula for Non Uniform magnetic field region in which we place same type of loop??
Well Explained 🙂
Thank you teacher 🙏
No, you're awesome!
Sir how u can say that the distance travelled is h/cos@, although it's tilled(by thinking)the length of the portion ab should be fixed.particls have to travel the same magnitude but in a different direction, isn't it?
Particles are going up the loop which is being pulled to the right, so total distance traveled has both vertical and horizontal component
your awesome man!
❤
what is emf, is it work done, or voltage.?
we got emf to be equal to IV from ohm's law.
Lets Forget Faradays Law!
-Done.
U dont tell the main reason only read the book page and translate ...
My philosophy: (1) The only person who can learn is YOU. (2) YOU need to be exposed to information in many different formats to help encourage your brain to work on the problems.
If I solve the problems for you, I am depriving you of the ability to learn physics. YOU need to let your brain reprogram itself until you see that this is really the best way to present the material. I won't interfere with what has to happen in your brain!
@@jg394 Hey man, Great philosophy! I'm a brazilian student and i'm going to graduate next year in physics. I really really apreciate what you're doing here, your lessons help a lot with theory. Thank you very much. I'm never gonna meet you, but I admire you philosophy and intentions. Best regards from Brazil.
Dude I don't want to read whole book so I come to him and if you also want to review your class you can see his video
Sir you are just reading the book and translating
And what is wrong with that exactly?
@@ryankim1999 Because we can read book on our own, we came here to learn in more explanatory manner!
Warner brothers hahaha awesome
