description The invention discloses a preparation method of a high-magnetism anti-cracking magnetic material. The method is characterized in that anti-cracking magnetic fiber and porous composite filler are addedin the process, and the preparation method comprises the following steps: step 1, weighing the following raw materials in parts by weight: 1-3 parts of cobalt sesquioxide, 1-2 parts of magnetic fiber, 2-5 parts of lanthanum oxide, 0.5-1 part of porous composite filler, 1-2 parts of activated strontium carbonate, and 100-150 parts of a base material; step 2, mixing and heating cobalt sesquioxide,lanthanum oxide and active strontium carbonate until being molten, preparing a molten metal solution, and then pouring the molten metal solution into a mixed metal block; step 3, placing the mixed metal block in a hydrogen decrepitation device, preparing metal particles with the particle size being 0.5 mm or below, enabling the metal particles, the base material and the porous filler to be subjected to airflow powder grind
