ABSTRACT
We present a mechanism to produce X-ray transient periodic variations in AGN. This mechanism is triggered o by Compton scattering in the infalling plasma into a black hole, which can induce an electric charge in the singularity. The charging and discharging processes can a ect the X-ray luminosity of AGN.
