Abstract: The present invention belongs to the field of functional fibrous materials, and discloses a magnetic fibrous material and a preparation method and application thereof. A polymer and a magnetic load raw material are dissolved in a solvent to obtain a uniform spinning solution; a solute component that reacts with the magnetic load raw material is added into a coagulation bath solvent to obtain a reactive coagulation bath solution; the spinning solution is electrospun, and the produced fiber is collected with the reactive coagulation bath solution, so that the magnetic load raw material in the fiber reacts in situ with the solute in the reactive coagulation bath solution to obtain the magnetic fibrous material.
