Abstract:
A soft magnetic member is formed such that, when a differential relative permeability in an applied magnetic field of 100 A/m is represented by a first differential relative permeability μ′L, and when a differential relative permeability in an applied magnetic field of 40 kA/m is represented by a second differential relative permeability μ′H, a ratio of the first differential relative permeability μ′L to the second differential relative permeability μ′H satisfies a relationship of μ′L/μ′H≦10, and a magnetic flux density in an applied magnetic field of 60 kA/m is 1.15 T or higher.
