S is the reluctance of path BE

AT required for portion BAFE (=26cm) = ϕ × S 3
AT required for portion BE = ϕ × S 1

In the electric circuit, we see that by applying KCL
E − IR − I R = 0

1
or E = IR + I R 1

Similarly, for the magnetic circuit
Total AT = AT required for portion BAFF + AT required for the portion BE
= 3105 + 862
= 3967.
The number of turns of the exciting coil is 800.
