ABSTRACT:
A ferrite magnetic powder for bond magnet that experiences only small decrease in coercivity when molded into a bond magnet is provided, which is a ferrite magnetic powder that includes an alkaline-earth metal constituent and exhibits a decrease in coercivity of not greater than 600 Oe when subjected to a prescribed molding test. The magnetic powder can be obtained by mixing a fine ferrite powder of an average particle diameter of greater than 0.50 to 1.0 μm and a coarse ferrite powder of an average particle diameter of greater than 2.50 to 5.0 μm at ratio to incorporate the fine powder at a content ratio of 15-40 wt %.
