The invention relates to a magnetic powder core, a mould pressing inductor and a manufacturing method of the magnetic powder core and the mould pressing inductor and belongs to the technical field ofpowder metallurgy and magnetic materials. The magnetic powder core is manufactured by sequential compression moulding and thermal treatment of coating powder prepared from raw materials of iron-basedcomposite powder, a binder and a lubricant; the mould pressing inductor is manufactured by embedding a pre-wound coil in the coating powder prepared from the raw materials of the iron-based compositepowder, the binder and the lubricant prior to integral moulding; the iron-based composite powder comprises, by weight, 70-95wt% of iron-based amorphous alloy powder A and 5-30wt% of iron-based amorphous alloy powder B; the iron-based amorphous alloy powder A is prepared by subjecting iron-based amorphous alloy strips to brittle heat treatment, mechanical crushing treatment and airflow crushing treatment; the iron-based amorphous alloy powder B is prepared by allowing the grain size o f the powder A or the powder B to be smaller than or equal to 30 microns. With the method, the magnetic powdercore manufactured is good in soft magnetic property and temperature rise of the mould pressing inductor is low.
