For the small rectangular loop with sides a and b that carries a current I, shown in Figure.

a) Find the vector magnetic potential A at a distant point, P(x, y, z). Show that 1t can be put in the form of Eq. (6 - 45).

---

b) Determine the magnetic flux density B from A, and show that it is the same as that given in Eq. (6-48).
