Magnetic Circuits with Air Gap || End Chapter Problem 1. 9 (Fitzgerald) || Em 1.2(1)

Em 1.2(1)(English) (Fitzgerald)
Question 1. 9 : The magnetic circuit of Fig. 1.26 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 (/z --+ c~) and neglect the effects of
magnetic leakage and fringing. For:
Ri -- 3.4 cm
Ro = 4.0 cm
h-2cm
g = 0.2 cm
calculate:
a. the mean core length lc and the core cross-sectional area Ac.
b. the reluctance of the core ~c and that of the gap ~g.
For N = 65 turns, calculate:
c. the inductance L.
d. current i required to operate at an air-gap flux density of Bg = 1.35T.
e. the corresponding flux linkages ~. of the coil
