| Abstract: | In this paper we have studied in detail (numerically) the trajectories of charged particles in a magnetic field (dipolar at
infinity) associated with a static star in the framework of Rosen's bimetric theory of gravity. It was found that there do
exist potential wells that allow possible trapping of particles in stable orbits both on and off the equatorial plane. A particularly
interesting feature that has shown up is the fact that the characteristics of the effective potential wellV
eff depend on the ratio of the magnetic field strength parameter λ, and the angular momentumL of the charged particle. For values lower than a critical (λ/L)
c
the potential well lies within the regionr≤2m. |
