Q. Consider themagnetic circuit of Figure. Let the cross-sectional area AC of the core, be

16 cm² , the average length of the magnetic path in the core lC be 40 cm, the number of turns N of the excitation coil be 100 turns, and the relative permeability µr of the core be 50,000.

For a magnetic flux density of 1.5 T in the core, determine:

(a) The flux φ

(b) Total flux linkage λ(= Nφ).

(c) The current required through the coil.
