Question
In the magnetic circuit shown in Fig. 1, a coil of 500
turns is wound on the central limb. The magnetic
path from A to B by way of outer limbs have a mean
length of 100 cm each and an effective cross-
sectional area of 2.5 cm2
. The central limb is 25 cm
long and 5 cm2 cross-sectional area. The air gap is
0.8 cm long. Calculate the current flowing through
the coil to produce a flux of 0.3 m Wb in the air gap.
The relative permeability of the core material is 800
(neglect leakage and fringing).
