PROBLEM TO BE SOLVED: To provide a powder for powder magnetic core which has permeability that becomes largest and used for transformers, inductors, motors or the like. SOLUTION: The powder for a powder magnetic core is specified with its average aspect ratio (Ma) being set so as to satisfy the formulas, 30<=Ma<=100, (0 Oe<=Hn<=10 Oe), 20<=Ma<=50 (10 Oe<Hn<=20 Oe), 10<=Ma<=30 (20 Oe<Hn<=30 Oe), and Ma<=20 (30 Oe<Hn), corresponding to a DC magnetic field (Hn) applied to a magnetic core material. |
