Re: Inductance and the acceleration of charge

I second that statement! It is the "bible" for inductance calculations. I got my copy after Pauls work with the TSSP and Geotc (because I wanted to understand "how" Paul pulled Grover into Geotc from a code writing perspective). I had to figure out the interpolation method which is something I had not done before, but after I understood, it all worked out perfect. I still remember the grin on my face when I used a pencil and paper on the first calculation I had selected. It amazes me how much time and effort must have been made to derive the tables and methods for such a dynamic array of geometry.

Take care,
Bart

I recommend that anyone seriously interested in calculating inductance get a copy of the book by Frederick Grover, Inductance Calculations: Working Formulas and Tables, Dover Publications, Inc., New York 1946. Used copies are still available if you dig around. A lot of the material here is about the same as in the much older BS C74 and is in more convenient form. There is a useful procedure for calculating inductance in a letter from Richard Lundin in the PROC. IEEE, V75 #9, 9/85, PP1428-1429. Claimed to be accurate to about 3 ppm for solenoids of any form factor. If anyone is really seriously interested I can send him an Excel worksheet which compares several different familiar inductance formulae to the values given by Lundin's expressions.

Wheeler's two formula are still plenty accurate for any hobby work that I can think of.
