PURPOSE : A magnesium amorphous alloy magnetic material is provided to improve durability by providing a magnetic material of magnesium alloy series. CONSTITUTION : A general formula is Mg100-x-yAxBy(x, y is atomic weight %, 2.5<=x<=35, and 2.5<=y<=40). The A of the general formula is one or more metals selected from transition metals including Cu, Ni, Co, Zn, Al and Ag. The B is one or more elements selected from rare earth elements including Gd, Nd, Tb, Er, Dy, Ho, Tm and Sm. A manufactured magnesium amorphous alloy magnetic material has a maximum saturation magnetization value over 10emu/g.
