I think Mr. Faraday would be very surprised to hear this. Think about the secondary of a transformer. How does that coil know where the flux is coming from? It just has flux in it. So why is that any different from any other coil in a magnetic field? Are you saying the only source of a...

Hope this helps.
So far, really like this forum. I just need to master the gentle art of asking responders to stay on topic - kind of like herding chickens. Oh well.
Can you advise how to tell if a thread is closed? So far I have not seen how this is designated. Also, if I make a request to have a thread...
Dear moderator - sometimes a thread gets so full of irrelevant information that it is no use to anybody, including the OP. The problem is nobody is going to read it, even if there is a useful answer buried at the bottom. Frustrating.
I would like to close it and start a new thread asking...
Yeah, that's how circuit analysis is done - you have real and imaginary components, or resistive and reactive. That's why (R + XL) is correct. You don't have to square them.
I really appreciate all of the comments I have received. At this point can we throw this open to other electronics...
My guess is the solution lies in this formula
I = VS / (R + XL)
I wish I could give a dollar to the first person who can draw the circuit correctly and give me a complete solution. It may be that VS is a voltage source that is a function of webers.
Sorry, but it doesn't help and I hope there are other solutions out there. If you have a coil with two terminals and you short them together, clearly you can't have infinite current, so how does this help me? I tried to make this clear in my OP.
I just added the schematic to my OP. To technician, if you have a solution that uses Faraday's law, by all means post it. I would like to focus on the solution to my problem. Thanks!

Only seems to appear when you reply or edit your post. Correct?
In all the tutorials I have seen on inductance and magnetism, I have never seen how to represent an inductor as a voltage or current source in a circuit. Please see figure. I am trying to determine V and I given the characteristics of the coil and the magnetic flux through the coil.

This is my first post. The sticky on Latex is very useful. Looks like I will be learning the code for formulas. Would like to know if you can test the code without posting to the board - how to play with the code and view results locally first.
I am also trying to attach an image. Darn -...
