Contribution

It introduces a model of particle dynamics on rotating Archimedean spirals within wormhole metrics, analyzing phase space to understand escape conditions.

Findings

Particles can reach force-free regimes within the wormhole.

The physical parameters significantly influence particle trajectories.

Particles may escape the wormhole under certain conditions.

Abstract

A particle moving on curved magnetic field lines in the wormhole metrics is considered. The dynamics of a single particle is studied on a co-rotating parameterized magnetic field line. Being interested in the force-free dynamics we choose the rotating Archimedes' spiral embedded in the generalized Ellis-Bronnikov metrics. By analysing the phase space, we explore how the physical parameters affect the motion of the particle and it is shown that the particles may reach the force free regime, eventually escaping the wormhole.
