Abstract
A magnetic core making use of an Fe-based amorphous alloy ribbon that simultaneously attains miniaturization and noise reduction through realization of high B; and an applied product making use of the same. There is provided a magnetic core making use of an Fe-based amorphous alloy ribbon, wherein the saturated magnetic flux density (B) of the Fe-based amorphous alloy ribbon is ≧1.60 T and wherein the ratio between magnetic flux density at a core external magnetic field of 80 A/m (B) and Bof the Fe-based amorphous alloy ribbon, B/B, is ≧0.90.
