A) the current of the second winding to establish a flux of % millivber with the direction shown in the air gap? Suppose the nucleus is in the linear region and its magnetic diffusion coefficient H = H Ho = 0.002 in the international system of units is ( SI). B) Calculate the energy stored in the core magnetic field for the information in paragraph A. C) Determine the self-induction and cross-induction coefficients of the windings D) If the coil is 400 Connect the circuit to the single-phase voltage of city vi(t)=220V2 sin314t, specify the voltage of the second winding in the open circuit mode.
