We investigate the trajectories of charged particles moving in a space modeled by the 3-space M2(c) x R under the action of the Killing magnetic fields. One explicitly determines all magnetic curves corresponding to the Killing magnetic fields on the 3-dimensional Euclidean space (c=0). See [1]. We give the local description of the magnetic trajectories associated to Killing vector fields in S2 x R, providing their complete classification (c=1). Moreover, some interpretations in terms of geometric properties are given. See [2]. Then, the geometry of normal magnetic curves in a Sasakian (respectively cosymplectic) manifold of arbitrary dimension is explained. Some results about the reduction of the codimension of a normal magnetic curve in a Sasakian space form are given. See [3].
