We conducted a research on spin currents in a Na-23 spinor Bose-Einstein condensate (BEC) by applying a magnetic field gradient. The spin current was successfully induced by the spin-dependent force generated by the magnetic field gradient. We studied the dynamics of the spin components under the influence of the magnetic force. This study holds promise for generating longer spin coherence and enhancing the sensitivity of spin-mixing interferometry in a spinor BEC.
