magnetic ring

For the magnetic ring of Prob. 2.11, the exciting current is again 3 A. Find the following:

(a) Inductance of the coil,

(b) energy stored in the magnetic material and in the air-gap, and

(c) rms emf induced in the coil when it carries alternating current of 3 sin 314t.

Prob. 2.11:

A ring of magnetic material has a rectangular cross-section. The inner diameter of the ring is 20 cm and the outer diameter is 25 cm, its thickness being 2 cm. An air-gap of 1 mm length is cut across the ring. The ring is wound with 500 turns and when carrying a current of 3 A produces a flux density of 1.2 T in the air-gap. Find (a) magnetic field intensity in the magnetic material and in the air-gap. (b) relative permeability of the magnetic material, and (c) total reluctance of the magnetic circuit and component values.
