摘要：In the current research to investigate, the effect of size Fe3O4 granules on mechanical and magnetic properties magnet composite material with Fe3O4 filler. The Fe3O4 composite magnetic binder uses a Polyvinil Alcohol (PVA) matrix. The manufacturing process using the vacuum infusion (MIV) method. The variations in the size of the Fe3O4 grains used are 200, 225, 250, 300 mesh. And the weight fraction (% Wt) of PVA and Fe3O4 particles is 40% : 60% of the specimen weight of 10 grams. Testing of mechanical properties in the form of testing bulk density and compressive strength, testing of magnetic properties in the form of testing remanent induction values (magnetic remanence (Mr), coercivity (Hc), and maximum product energy (BHmax).The results of testing remanent induction values (Mr) ,Hc, BHmax and total calculations confirm the hypothesis that the 225 mesh sample (largest grain size) has better magnetic properties than the other samples.
