Abstract

See full text

A method for producing a powder magnetic core includes applying energy to a surface of a soft magnetic powder coated with an insulator, exposing the soft magnetic powder to an atmosphere having an atmospheric pressure dew point of −30° C. or higher and 15° C. or lower, and forming a molded body by pressing the soft magnetic powder at 20 MPa or more and 400 MPa or less.
