Based on the inverse Faraday effect, light-induced magnetization field distributions are investigated for a 4π tight focusing configuration with azimuthally polarized beams. It is found that superlong (16λ) chain, composed of 19 subwavelength (0.44λ) spherical spots longitudinal field, can be achieved in focal volume objective. Moreover, magnetic force particle or trains produced by tightly focused beams calculated and exploited stable trapping particles. These unique may find potential applications confocal microscopy, atom control, magneto-optical data storage.
