description	The invention discloses a core-shell heterostructure magnetic fiber and preparation and application methods thereof. The fiber is composed of, by atomic percent, 12.2%-29.6% of Fe, 9.2%-55.2% of Cu and 32.5%-70.5% of C. According to the structure of the core-shell heterostructure magnetic fiber, the core-shell heterostructure magnetic fiber is a Cu/F3/C core-shell structure nanofiber composed of Cu/Fe cores and C shells with a hollow or porous structure, the length of the fiber ranges from 50 micrometers, and the diameter of the fiber ranges from 70 nm to 380 nm. The saturation magnetization strength of the fiber ranges from 80.4 emu.g to 152.89 emu.g. The fiber is prepared through an in-situ carbon thermal reduction-chemical chemical vapor deposition method, that is, organic polymer coated Cu2O core-shell heterogeneous nanofibers and pentacarbonyl iron are contained by a ceramic ark and placed in a tube furnace, and calcinations is carried out under inert gas shielding. The core-shell heterostructure
