Two parallel, circular loops carrying a current of 20 A each are arranged as shown in Fig. 1. The first loop is situated in the x−y plane with its center at the origin, and the second loop’s center is at z = 2 m. If the two loops have the same radius a = 3 m, determine the magnetic field at:

(a) z = 0

---

(b) z = 1 m

---

(c) z = 2 m
