Abstract: (arXiv)

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.
