The weight percentages of the main material components and additive components of the magnet tile are as follows: main material: 8.7%～9.0% strontium oxide; 86%～87% iron red, additive: 0.6%～1.0% calcium carbonate, 0.6 %～1.0% aluminum oxide, 0.4%～0.8% chromium trioxide, 0.3%～0.6% boric acid, 0.3%～0.5% silicon dioxide, 0.2%～0.4% cobalt tetroxide, 0.2%～ 0.4% lanthanum trioxide and 0.1% to 0.3% silicate fiber. The invention not only has high residual magnetic induction intensity, but also has high intrinsic coercivity, and can improve the mechanical strength of the magnetic tile.
