AB  - <jats:p>                    We present a magnetic trapping scheme for cold                    <a:math xmlns:a="http://www.w3.org/1998/Math/MathML">                      <a:mmultiscripts>                        <a:mi>Rb</a:mi>                        <a:mprescripts/>                        <a:none/>                        <a:mn>87</a:mn>                      </a:mmultiscripts>                    </a:math>                    atoms based on light-induced fictitious magnetic fields generated by the evanescent field of an optical nanofiber (ONF) integrated with optical tweezers. We calculate and compare the trapping potentials for both Gaussian and Laguerre-Gaussian modes of the tweezer beam, combined with a quasilinearly polarized ONF-guided field. Based on the optical powers in the tweezer and ONF modes, we analyze the trap depths and the positions of the potential minima from the nanofiber surface. We show that, by varying the optical powers in the two fields, the trap position can be tuned over several hundred nanometers while simultaneously influencing the trap depth and trap frequencies. Such control over the atom-surface position is essential for studying distance-dependent effects on atoms trapped near a dielectric surface and optimizing atom-photon interfaces for quantum technology applications.                  </jats:p>
