  ABSTRACT: It has recently been postulated that protons are accelerated up to energies offrom nearby Seyfert galaxies which harbor Kerr holes in the center of their hosts. Here, we point out that the relativistic force equation of protons is governed by the Lorentz force when using the post-Newtonian approximation. The synchroton emission from nonthermal relativistic protons has to be ruled out. We carefully discuss the origin of the magnetic field close to the event horizon of a black hole.
