Bohr quantum theory of the magnetic monopoles and classical electron electromagnetic mass problem

In the first part of this work we apply Bohr (old or naive quantum atomic) theory for analysis of the remarkable electro-dynamical problem of magnetic monopoles. We reproduce formally exactly some basic elements of the Dirac magnetic monopoles theory, especially Dirac electric/magnetic charge quantization condition. It follows after application of Bohr theory at the system, simply called magnetic monopole atom, consisting of the practically standing, massive magnetic monopole as the nucleus and electron rotating stable around magnetic monopole under magnetic and electrostatic interactions. Also, in the second part of this work we suggest a simple solution of the classical electron electromagnetic mass problem.
