However, in the case of a magnetic core made of laminated tape-shaped amorphous soft magnetic material, the cross section of this magnetic core is inevitably square, whereas the winding state of the coil wound around this magnetic core is essentially circular. Therefore, when a transformer or a choke coil is formed using such a magnetic core and coil, there is a problem in that a magnetic flux gap is likely to occur between the magnetic core and the coil.

In addition, as long as the cross section of the magnetic core is square, no matter how close to a circle the coil is wound, the magnetic flux distribution in the magnetic core will not be uniform in the center and periphery, and due to this non-uniform magnetic flux distribution. There is a problem that high frequency characteristics are inhibited.

On the other hand, in the case of small-sized, low-power magnetic cores, it is also possible to make the amorphous tape tapered at the beginning and end of the winding so that the cross section of the completed magnetic core has a circular shape.

Also, referring to silicon steel sheets, silicon steel is a soft magnetic material with excellent magnetic properties, but the more Si it contains, the worse its mechanical properties are, and its malleability is poor and it has almost no ductility, so it is easily broken. Therefore, such silicon steel has a thickness of 50 μm.
It is best to have a plate-like core, and it is impossible to make it into a wire, so it was inevitably impossible to manufacture a wire-like silicon steel magnetic core.
