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 (µ ?
) and neglect the effects of magnetic leakage and fringing. For:

calculate:
a. the mean core length l
and the core cross-sectional area Ac.
b. the reluctance of the core ~c and that of the gap Rg. 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.
