1.47 It is desired to achieve a time-v the magnetic circuit of Fig. 1.41 of the form where Bo = 0...
2. The magnetic circuit of Fig. 1 consists of rings of magnetic material in a stack of height h. The rings have inner radius Ri and outer radius Ro. Assume that the iron is of infinite permeability (μ → x) and neglect the effects of magnetic leakage and fringing Ri N turns For Ri-3.2 cm, Roー4.1 cm, ћ-1.8 cm, g = 0.15 cm, N-72 turns, calculate a. The mean core length le and the core corss-sectional area Ac. b. The...
