The invention discloses a ferrite magnetic material used in electrical engineering. The ferrite magnetic material is prepared from the following raw materials: iron oxide, copper oxide, zinc oxide, lanthanum oxide, strontium oxide, nickel oxide, cobalt oxide, citric acid, carboxymethyl cellulose, calcium carbonate, and organosilicone. The ferrite magnetic material, which is reasonable in formula and is prepared by pre-sintering, crushing, molding and sintering, has the advantages of high performance and high orientation; by the steps of firstly pre-sintering oxide in the raw material under oxygen condition, crushing and mixing citric acid, carboxymethyl cellulose, calcium carbonate and organosilicone, the pores of the material are decreased, the uniformity of the material is increased; and by gradient heating during the sintering and firstly cooling and then heating after the sintering is completed, the uniformity and degree of orientation of the material are improved.
