umm, non that I can think of at the moment. If what I said was correct, then not really, maybe later I will have some question after I think about it more. Thanks a bunch for helping to at least get a big picture idea of what is happening.

Well I was just looking for a big picture of how it works, I have no idea how it works at like the very fundamental level. As for the transmitter, wouldn't the receiver be so far away from the transmitter, like several miles, that the near field effects would be practically nothing? I have read...

So are you saying that the voltage shouldn't decrease to zero since that would mean the current returning to zero? What did you mean exactly by this t_n_k: "new condition would exist where (upon reaching steady state) there is a constant alternating current flowing in the closed circuit by...

yea I was just thinking about this in a ideal type of way to make it easier to figure out what happens. what did you mean by this t_n_k? "I'd start by considering an open secondary winding substantially isolated from the primary flux source but still enclosing all the primary flux (a nonsense I...

Yea that would be pretty awesome, I assume you mean something like paint imbedded on the page instead of having to upload image's.

Ok, I get what your saying, the amp-turns is the important thing to look at but ultimately it is the current that generate's the magnetic field and depending on the wire resistance, you eithier need a higher or lower voltage to get the same current through the wire. So it is the current that is...

I know there are a bunch of other things that effect the magnetic strength but What i meant was that between the voltage and the current, the current ultimately generates the magnetic field, the voltage just causes the current to flow, right? Or can a high voltage and low current generate the...

lol, if what you said #12 is correct about price, then I will have to build a much smaller one. The big reason for asking this about heat was because the way I was thinking the electromagnet was going to be built was multilayered since you cannot just have that many turns in a single layer. So...

Thanks for the answers, I tried looking up the advanced field but I couldn't really find anything on it, just advanced physics and stuff. I did find this from wiki though. http://en.wikipedia.org/wiki/Field_%28physics%29#Continuous_random_fields The part on Propagation of static field...

I was assuming in space, so any force generated on either would always cause them to move and thus have momentum. Also I actually thought that might be one way it happens, that the field lines have already stretched out, so when the other magnet encounters the field, it feels a force and thus...
