- A modern (?) way to calculate the inductance could be to use a finite-
- element basedelectromagnetic field solver. A good solution, if you have
- the program available and the time to read through that half a meter
- thick pile of documentation. I am not sure abut the precicion of the
- calculated inductance, but I guess you could get to within 1e-3 or
- better of the correct value. The more cpu time and elements you use,
- the better the results will be.

- From a circuit analyzer program manual I found the following reference
- for analytic expressions an approximations used in calculating the self-
- inductance of a solenoid.

- F. W. Grover, Inductance Calculations,
- Dover Publication, 1973 (first printing 1946)

- It is claimed to be a book for engineers seriously interested about
- inductance... Haven't read it, so I won't comment on that.
