Abstract
A closed form analytic solution is found for the electromagnetic field of the charged uniformly rotating conducting disk for all values of the tip speed $v$ up to $c$. For $v=c$ it becomes the Magic field of the Kerr-Newman black hole with $G$ set to zero. The field energy, field angular momentum and gyromagnetic ratio are calculated and compared with those of the electron. A new mathematical expression that sums products of 3 Legendre functions each of a different argument, is demonstrated.
As a slight counterpoint (I haven't looked into the claims of the patents too much): There is the well known Kerr-Newman solution of a rotating, charged black hole. It is well known that a relativistic rotating charged disk approximates in the limit of (v = c) the Kerr-Newman…
