Core Flux
The air gap flux is the same as the core flux as the whole of the core flux
crosses the air gap and there is no fringing.
Example 5.7 A parallel magnetic circuit with 2000 turns on its central limb
has been shown in Fig. 5.27. The air gaps are 2 mm each. The mean diameter
of the circular magnetic path is 20 cm.

The cross-sectional area of the central limb is 10 cm while the cross section

of the outer limbs is 5 cm . A few readings from the magnetization curve are
given below.
