  • Device comprising a core consisting of parts of amorphous ferromagnetic metal and parts of non-amorphous ferromagnetic material
    Patent number: 4739294
    Abstract: A device having a core that comprises a bar-shaped leg (1) of amorphous ferromagnetic metal which is surrounded by a coil (7), and a yoke (3) which magnetically interconects the end portions of the leg and which is made of ferrite. The cross-sectional area of the yoke (3) is at least twice as large as that of the leg (1). This construction combines the advantages of the low core losses of amorphous metal and a low cost price.
