Re: Equivalent lumped inductance and toroidal coils

Sorry, a typo in the previous post, the mutual
inductance between the filaments should be

  M = pi * mu * Xa * sin(alpha) * sin(beta)
      * sum{ for n=1 to infinity;
             (Xa/Xb)^n / (n*(n+1))
              * Pn( cos( alpha)) * Pn( cos( beta)) * Pn( cos( gamma))}

Funny how you only see these after hitting the send key.
