The square loop shown in Fig. 1 is coplanar with a long, straight wire carrying a current

 i(t) = 2.5 cos 2π × 104 t (A)

(a) Determine the emf induced across a small gap created in the loop.

---

(b) Determine the direction and magnitude of the current that would flow through a 4-Ω resistor connected across the gap. The loop has an internal resistance of 1 Ω.
