1.1 A magnetic circuit with a single air gap is shown in Fig. 1.24. The core dimensions are: Cross-sectional area A. = 1.8 x 10-³ m² Mean core length 1c = 0.6 m Gap length g = 2.3 × 10-³ m N = 83 turns N turns Core: mean length l area A permeability Air gap Figure 1.24 Magnetic circuit for Problem 1.1. Assume that the core is of infinite permeability (→→∞o) and neglect the effects of fringing fields at the air gap and leakage flux. (a) Calculate the reluctance of the core Re and that of the gap Rg. For a current of i= 1.5 A, calculate (b) the total flux p. (c) the flux linkages of the coil, and (d) the coil inductance L.
