    In Dr. Mark Rzeszotarski's Tesla Coil Frequently  Asked Questions 
("Chapter 7: The Primary Coil", Father Tom McGahee's Q&A  section, pg 37) :
 
    "Since k=M/sqrt(Lp/Ls) ... What is not so obvious  is the fact that M is 
proportional to Np times Ns for most coil geometries we  use in a tesla [sic] 
coil (solenoid, flat pancake, inverted cone, for five or  more turns in the 
primary). As a result, by keeping the same geometry and only  varying the number 
of turns, K remains constant since as Lp and Ls vary, so  too does M." 
 
    Didn't Dr.Rzeszotarski develop the "MandK"  program?
