MH's ideal coil and voltage question

[Pirate88179]

I don't understand what you mean. I'm saying EMF is a result of current. Well, 'result of' is not quite what I mean but it's hard for me to word it otherwise.

How can there be an electromagnetic field without current? There is however an electric field, the voltage.


-maybe I have this wrong but I think you may be missing that we are essentially saying the same thing. damn maybe MH is right and I need to start honing my word choices.

EMF=Electro-Motive Force not electromagnetic field...maybe this will help your confusion?

you are right thank you I was just realizing that

(i will admit I really need to brush up on what to call certain things MH! but in theory I feel
I understand what is going on.. for example I want to call the voltage the electric field in nature when that's not even correct after checking)

No problem.  This can be very confusing...and...just when I think I am starting to understand something...I find out that I really am not, ha ha.

it is indeed very confusing and hard to convey thoughts without looking like an idiot if you're like
me and have not dedicated enough time to properly learning the right terminology for everything.
but in an even harder way to explain it seems like this argument involves a basic paradox that
was at least evident enough to warrant many pages of debate. at the end of it all while I personally
struggle to convey my thoughts, I just think the damn thing will do absolutely nothing. Sit at source voltage and act as if it wasn't even there to begin with.

I thought the EMF followed current.

An EMF measured across an open inductor is proportional to the rate of change of flux penetrating that inductor (dΦ/dt).
EMF measured across an inductor is not proportional to the current flowing through it and in an open inductor the current cannot flow at all.

It's the electric field that's the precursor.

Precursor of what?
