So I'm having some trouble with the whole electromagnetic field line stuff - always have. Some may have heard me say I don't believe in 'em. I mean, the two are interchangable, yet the physical transformation is irreconcilable from a visual standpoint, yet they're inherently a visual aid.

Then a in the E-Mag textbook by Good, he states that field lines are useful but have no physical presence after explaining the relativistic qualities of a moving wire with current.

So of course I take the opposite stand and say, but what if the lines were there?

The best I can do is figure electromagnetic field lines must be gyroscopic in some sense. . . anyone out there got a visual on a one-dimensional gyroscope? How about a line unfolding to a coil due to compresion? Any commments on how to run with this analogy would be helpful.
