<P>PROBLEM TO BE SOLVED: To provide a magnetic core, along with an application article using the same, which uses an Fe radical amorphous alloy thin band that satisfies both small size and low noise due to high B<SB>S</SB>. <P>SOLUTION: The magnetic core uses an Fe radical amorphous alloy thin band, and the saturation magnetic flux density Bs of the Fe radical amorphous alloy thin band is ≥1.60 T. The ratio B<SB>80</SB>/B<SB>S</SB>is ≥0.90, where B<SB>80</SB>is the magnetic flux density at the magnetic core when external magnetic field is 80 A/m, and B<SB>S</SB>for Fe radical amorphous alloy thin band. Thus, the magnetic core is provided whose magnetic flux density is 1.4 T and iron loss W<SB>14/50</SB>at frequency 50 Hz is ≤0.28 W/kg. <P>COPYRIGHT: (C)2007,JPO&INPIT |
