Dependencies of core loss (a) and initial magnetic permeability (b) on frequency. (1) Core annealed in furnace (T a  = 550°C, t a  = 90 min). (2) Core made of ribbon heated by electric current (j h  = 42 A/mm2, t h  = 3.7 s) under tensile stress 100 MPa. (3) Cut core with non-magnetic gap 0.045 mm (T a  = 550°C, t a  = 90 min).
