Abstract
We consider the role of centrifugal force on the energetics of
electrons moving along the magnetic field lines of spinning active
galactic nuclei. We find the energy gained by charged particles
against inverse Compton scattering and/ synchrotron radiation losses,
become quite significant in the region close to the light cylinder.
The particles accelerated by the centrifugal force become a part of
the jet material. The scattering of UV-photons against the energetic
electrons lead to the generation of X-ray and ![[FORMULA]](img1.gif)
-ray photons within the light cylinder, and outside, they radiate the
non-thermal optical radiation via the synchrotron emission.
