In the theory of curves, a magnetic field generates a magnetic flow whose trajectories are curves
called magnetic curves. This paper aims at studying some properties for these curves which corresponding
to the Killing magnetic fields in the 3-dimensional Euclidean space. We investigate the trajectories of the
magnetic fields called T-magnetic and e-magnetic curves, also we give some characterizations of these curves.
In addition, we determine all magnetic curves for new spherical images of a spherical curve and finally, we
defray some examples to confirm our main results.
