-10/6 A magnetic circuit, composed of two half-rings of different core materials, is joined at the ends to form a doughnut. The cross-sectional area of the core is 0.14 m, and the reluctances of the two halves are 650 A-t/Wb and 244 A-t/Wb, respectively. A coil of 268 turns and 5.2-2 resistance is wound around the doughnut and connected to a 45-V battery. Determine (a) the core flux; (b) repeat (a), assuming the half-rings are separated 0.12 cm at each end (assume no fringing), and the reluctance of the half-rings does not change; (c) the magnetic drop across each air gap in (b).
