A bar of an iron–silicon alloy having the B–H behavior shown in Figure 18.29 is inserted within a coil of wire 0.20 m long and having 60 turns through which passes a current of 0.1 A.

(a) What is the B field within this bar?

---

(b) At this magnetic field, (i) What is the permeability?

(ii) What is the relative permeability? (iii) What is the susceptibility? (iv) What is the magnetization?
