It's shocking to me that AP Physics is apparently a lot more comprehensive than university physics, thanks for the explanation.

Nice video. I missed my lecture on Friday and this really helped out. In response to shazaduh4ever, if current is a function of time, it is independent of the dr, so pull it out of the integral anyway and just use the current at the specific point in time you want to observe. Your equation would look something like Flux(t) = uI(t)h/(2pi)*Integral(1/r dr) from r=a to r=a+L. In english: [(mu_not*current as a function of time * h)/(2*pi)] * integral of (1/r) dr from radius = d to radius = d+L

So how do you find the EMF from that flux? I'm confused on the math for the time derivative of the flux you have found and the flux I have found in my problem. I have a similar problem except that instead of using Amphere's law, they just gave us a function for the B field.
@shenanigans41776 жыл бұрын
Just differentiate the flux w.r.t t( time)

I'm not sure if you made a mistake in the commentary but at 3:30ish you say B is perpendicular to dA, but later on you say parallel. This had me a bit confused, but looking back on it I think you mean to say parallel because I don't think dot product cancels out for it being perpendicular

I thought that the magnetic flux is always equal to 0. So why is there an expression that we get? Is that expression equal to?
@lasseviren14 жыл бұрын
Sorry, the magnetic flux through a CLOSED surface must equal zero. An example of a closed surface is a sphere or a cube. But a surface that is not closed can have magnetic flux through it. An example of one of these surfaces might be one side of a piece of paper.

What if I wanted to find the induced EMF after the magnetic flux?
@lasseviren12 жыл бұрын
So you only have an emf if the magnetic flux is changing with time. To find it, use EMF = -d(flux)/dt or EMF(ave)=delta(flux)/delta(t).
@blakeangel83552 жыл бұрын
@@lasseviren1 yeah I have a similar problem to this one where I integrate from r=H to H+W but there is also a velocity on the loop going towards the current carrying wire. So if I am not mistaken I can use minus d fee over dt.
