Inputs:
R (coil radius)

H (coil height)

N (# of turns)

Outputs:

L (inductance)

l (wire length)

P (coil pitch)

Notes: top

Inductance is an empirical approximation AFAIK
Note that L doesn't depend on wire diameter!
Assumes a coil with only a few turns
Bruce Weber has compared this formula to one in Lorrain and Corson (E&M textbook) and found agreement when coil length > coil radius.

- My own formulae for length!
