The
figure shows a ferromagnetic core with a relative permeability of
2000. The dimensions are shown in the diagram and the core depth is
7 cm. The between irons on the left and right side of the core have
0. 050 and 0. 070 cm, respectively. Due to the marginal effects,
the effective area of the air gap increases by 5% with respect to
the physical area. If there is a 300-turn coil wound in the central
column of the...
