how is magnetite used in steel

Soft and Hard Magnetic Materials

High silicon sheet steel with a silicon content of about 4% is used chiefly in the magnetic circuits of power transformers which operate at flux densities of about 1 Wb/m 2 However, since the cores of rotating electrical machines are slotted with the teeth having a small cross-sectional area, the flux density in the teeth is much higher, of ....
