Subject: Re: [TSSP] MandK Mutual Inductance Program
Hello Mark,
Thankyou for sending me an advance copy (beta?) of MandK
a couple of years ago. I used it to confirm something I had suspected
for along time - that k is figure reflecting pure coil geometry and
proximity. The most striking prediction the program made (matched by
measurement within the usual error range) was on the coupling
constants present in Tesla's Colorado Springs machine (as noted by
Tesla and others) and an exact scale model of it that I built (has
since been torn to pieces).
Regards,
Malcolm
