Nevermind, you're probably right. Thank you very much for your time!

Sorry to bother but let me clarify something. In the picture I've posted (#12), isn't VA suppose to be zero since it's a point before the source? And in point B, if I follow the current's path from A to B, we first have a voltage rise of 10 V (the source) and then a voltage drop of 10 V (in the...

What do you mean? Thanks!

I believe see it now, thanks a lot! Like this? The VBA equals the VTh and VB = 10 V and VA = 0 V, right? Now, I'll try to add the upper right loop.

Hum, let's see. In that isolated upper left loop, Vth is equal to VAB = VB - VA , right? ( B being the node above E4) I thought VAB would be the V of the 2 ohm resistor, but I'm clearly confused. I believe it's a matter of not being able to visualize it correctly. Sorry for the trouble, do you...

Adding the other right loop: Rth = 7,4 ohm Vth = [ 10 * ( 2 / ( 2+ 4 + 1) ) ] + [ 2 * ( 2 / ( 2,5 + 0,5 + 3 + 2 ) ] V ? Thanks once again for your awesome support.

Thanks a lot for your guidance. For the upper left loop wouldn't it be: Rth = 7 ohm Vth = 10* (2/(2+4+1) ) V ? (Unfortunately the "B" node got cutted from the print. It's the "R" (a B without the lower leg) under E1)

Hello guys, Can someone guide me through this problems solution? I need to find the Thevenin's Equivallent for this circuit, between A and B. I'm terrible at Circuits and I'm eager for some motivation and help. Thanks a lot in advance.

Yes, it does!

Yes, inductance is a scalar quantity but I can make a projection of the ferromagnetic fiber along x and y, with a length and cross area also projected, calculate both Inductances Lx and Ly, and then the "final" inductance would be L = sqrt(Lx^2 + Ly^2).

Thank you!

This is awesome. Have you done it in Matlab? Would you be so kind to lend me the code you've used?

Yes I have. I'll try to explain this model. Imagine that a magnetomotive force is produced by a number of turns N and a current I, being Fmm=N*I. That magnetomotive force creates a magnetic flux ∅ that only crosses the ferromagnetic cylinder. The inductance of the ferromagnetic medium/fiber can...

My mistake, forgot to mention that the magnetomotive force is produced by a current I (constant). That's my current.

Perhaps you were right, but in any case, how can I relate this area that is crossed by the flux with the angle a? Thanks a lot for your help once again.
