to the primary side. Question # 3 The coils of the magnetic circuit shown in the figure are connected in series. They are wound with equa turns of 100 turns each. The dimensions are: Cross-section area of A and B legs 7 cm2 Cross-section area of C leg 14 cm? Length of A path is 17 cm Length of B path is 17 cm Length of C path is 5.5 cm Length of the air gap is 0.4 cm The material has a constant relative permeability of H of 2800. Neglect the fringing effect and leakage flux. 00 %3D Calculate the current required to produce a flux density of 1.2 T in the air gap.
