With regard to a spiral pancake (planar) coil, where do the EM and ES field lines emerge respectivley?
In other words, which from the flat surfaces and which from the circumferential edge.

What's your operating wavelength compared to wire length?
If much longer to DC, left-hand rule for the B field:
If the operating wavelength is shorter than the wire length you will have to figure out where the current nodes are. The antinodes make the field.
The ES field shape depends on the location and distance to other conductive objects are that are at easily definable voltages WRT those at various points on the coil.

One would think those were obvious.
What's EM and ES? The magnetic fields come from the currents. (Which I assume you already know.)

Electromagnetic and electrostatic.
How long have you been in this field?
OK and then how does electrostatic apply to a coil? Perhaps he's asking about near field and far field? or magneto-static. (Electro and magneto static are not great terms.. given that both fields can change in time.)
I've been in the Earth's B-field my entire life. :^)

I am not the one who posed the question you zero common sense twerp. get a clue. And you have a doctorate? Sheesh.
Perhaps you should address him with your guesses.
Just like a plot of an antenna's dispersion, he likely simply wants to know so he can place proximal components properly.
And you reversing the initials also shows that you are still guessing.
Nice try, vacuous dingledorf.
Why am I visualizing duct tape over your mouth?

Nice try, vacuous punk.
But not as permanent.
Because it's cheaper than lead?
