6.6 The square loop shown in Fig. P6.6 is coplanar with along, straight wire carrying a current I(t)=5 \cos \left(2 \pi \times 10^{4} t\right) (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 2 resistor connected across the gap. The loop has an internal resistance of 1 N.
