Question: For the circuit shown in Figure P13.10: a. Determine the reluctance values and show the magnetic circuit, assuming that μ = 3,000 μ0. b. Determine the inductance of the device. c. The inductance of the device can be modified by cutting an air gap in the magnetic structure. If a gap of 0.1 mm is cut in the arm of length l3, what is the new value of inductance? d. As the gap is increased in size (length), what is the limiting value of inductance? Neglect leakage flux and fringing effects. N = 100 turns A2 = 25 cm2 l1 = 30 cm l3 = 30 cm A1 = 100 cm2 A3 = 100 cm2 l2 = 10 cm Figure P13.10
