In the figure below, a wire forms a closed circular loop, with radius R = 5.3 m and resistance 5.7 Ω. The circle is centered on a long straight wire; at time t = 0, the current in the long straight wire is 7.0 A rightward. Thereafter, the current changes according to i = 7.0 A − (2.0 A/s2)t2. (The straight wire is insulated; so there is no electrical contact between it and the wire of the loop. ) What is the magnitude of the current induced in the loop at times t > 0? Number Units

This loop has radially oriented width a and axially oriented length b, and sits tight against the cylinder axis, as shown in (Figure 1).
